Differences Between Power Supplies, Inverters, and Transformers Differences Between Power Supplies, Inverters, and Transformers [0m:0s] [0m:4s] Hi I'm Josh Bloom, welcome to another video in the RSP Supply education series. In today's video we're going to be looking at some of the differences between several pieces of hardware that often get confused, even though they are intended for very different purposes. This hardware includes power supplies, [0m:23s] transformers, inverters, and voltage converters. [0m:28s] All of this hardware is intended to alter or change the type of power or voltage that you might be using. [0m:35s] The result you need will directly impact which type of hardware you may want to choose. [0m:41s] However, it is very common for people to confuse the different types of hardware. Let's discuss each type and what it is intended to do so hopefully by the end of the video you'll be able to have a very clear understanding of each and when you might want to use them. Let's first start with power supplies. A power supply can have many different functions, RSPSupply www.rspsupply.com 1-888-532-2706 www.youtube.com/RSPSupply [1m:2s] but most of the time the power supply is intended to take one type of power and convert it to another type of power. The most common example of this is a power supply that takes AC power and converts it to DC power. [1m:17s] While it is very common to use power supplies and industrial applications, one very common place you will see a power supply being used is for the gadgets you have around your home, such as your smartphone or laptop or tablet, RSPSupply www.rspsupply.com 1-888-532-2706 www.youtube.com/RSPSupply [1m:31s] or many other devices we use on a daily basis. You may have noticed that most of those devices come with a power chord with some sort of bulky block at the end of it. [1m:42s] This block is where you will typically find the power supply. [1m:45s] So, most of your devices do not actually use AC power, which is the type of power being supplied to your home. [1m:53s] These devices more commonly use some form of DC power. That little bulky block or power supply is what changes that AC power to the correct form of DC power for your device. [2m:7s] Power supplies can also be used for other purposes, such as conditioning power, which is basically a way to clear power of any interference or noise that might affect your electrical equipment. You also see power supplies that are used to convert one type of DC voltage to another type of DC voltage. However, in this case, you may see them referred to as DC power converters which we have here. [2m:32s] A DC power converter is a type of power supply. [2m:37s] One last type of power supply we will talk about is referred to as a UPS or uninterruptable power supply. [2m:45s] The UPS often works in conjunction with a standard power supply and is intended to continue to supply power to your load even when the input power is lost. [2m:57s] It is able to do this because it uses batteries to supply that power. [3m:1s] A UPS is a great option when your electrical equipment is performing important tasks that need to be continued in the invent of a power failure. Now let's talk about inverters. [3m:14s] Inverters work in a similar manner to power supplies with one major difference instead of converting AC power to DC power, the inverter does the exact opposite. It will RSPSupply www.rspsupply.com 1-888-532-2706 www.youtube.com/RSPSupply change DC power back to AC power. DC power is created by devices such as solar panels or batteries, but often we need AC power for the things that we commonly use. [3m:40s] For example, if you have solar panels on your roof, the power that is being created comes in a form of direct current or DC power. But, in our homes, most of the things that we need to power require alternating current or AC power. So in order to convert the DC power that is generated by the solar panels an inverter is used. [4m:4s] Lastly, let's talk about transformers. For more detailed information about how transformers, actually work, please see our other video which we will link in the description below. Similar to a power converter that is used for changing only DC power, a transformer is intended to be used with AC power. More specifically, transformers convert one type of AC power to a different type of AC power. For example, your home commonly uses 120 volts AC power. However, there are some electrical devices we use in and around our homes that need AC power, but cannot operate with 120 volts AC power. So, in this case, a transformer is used. If you have an automatic sprinkling system, chances are the valves in that sprinkling system require 24 volts AC power. To do this, a transformer converts 120 volts AC power that is available in our home to 24 volts AC power so that the sprinkler valves can operate properly. [5m:7s] Transformers come in many different shapes and sizes. It is important to note that transformers can both convert AC power up [5m:15s] and down, so if greater AC voltage is needed, a transformer will be used, and the same can be said when a lower AC voltage is needed. [5m:24s] So let's quickly recap. Power supplies most commonly convert AC power to DC power. Power converters are used to change voltage within the DC range only, and UPSs are intended to continue to supply power in the invent of a power failure and are often used with a regular power supply. Inverters are intended to change DC power back to AC power. And lastly, transformers are used to change one type of AC voltage to another type of AC voltage, up or down.

  • What Is an SMPS and How Does It Generate Harmonics?
    MIRUS FREQUENTLY ASKED QUESTIONS FAQ’s___ International Inc. 6805 Invader Cres., Unit #12, Mississauga, Ontario, Canada L5T 2K6 Harmonic Mitigating Transformers <Back to Questions> 4. What is an SMPS and how does it generate harmonics? The Switch-mode Power Supply (SMPS) is found in most power electronics today. Its reduced size and weight, better energy efficiency and lower cost make it far superior to the power supply technology it replaced. Electronic devices need power supplies to convert the 120VAC receptacle voltage to the low voltage DC levels Rectifier Lls that they require. Older generation power supplies used Bridge large and heavy 60 Hz step-down transformers to i convert the AC input voltage to lower values before ac Smoothing Switch-mode rectification. The SMPS avoids the heavy 60 Hz step- vac Capacitor dc-to-dc Cf converter down transformer by directly rectifying the 120VAC Load using an input diode bridge (Figure 4-1). The rectified voltage is then converted to lower voltages by much smaller and lighter switch-mode dc-to-dc converters using tiny transformers that operate at very high Figure 4-1: Typical circuit diagram of Switch-mode Power frequency. Consequently the SMPS is very small and Supply light. The SMPS is not without its downside, however. The operation of the diode bridge and accompanying smoothing capacitor is very non-linear in nature. That is, it draws current in non-sinusoidal pulses at the peak of the voltage Voltage waveform (see Figure 4-2). This non-sinusoidal current waveform is very rich in harmonic currents. Because the SMPS has become the standard computer power supply, they are found in large quantities in commercial buildings.

Donohue (2/14/07) Department of Electrical and Computer Engineering University of Kentucky Lexington, KY 40506 Updated by Stephen Maloney (2/12/08) (Lab 3 report due at beginning of the period) (Pre-lab4 and Lab-4 Datasheet due at the end of the period) I. Instructional Objectives Design and construct circuits that transform sinusoidal (AC) voltages into constant (DC) voltages. Design and construct a voltage regulator based on the characteristics of the Zener diode. Evaluate the performance of simple rectifier and regulator circuits. See Horenstein 4.3 and 4.4 II. Background Electric power transmits best over long distances at high voltages. Since P = I V, a larger voltage implies a smaller current for the same transmitted power. And smaller currents allow for the use of smaller wires with less loss. The high voltages used for power transmission must be reduced to be compatible with the needs of most consumer and industrial equipment. This is done with transformers that only operate with AC (DC does not pass through a transformer). However, most electronic devices powered by a home outlet require DC (constant) voltages. Therefore, the device must have a power supply that converts AC voltages into a DC (constant) voltage. The terminology "DC" is somewhat ambiguous. DC can mean the voltage or current always has the same polarity but changes with time (pulsating DC), or it can mean a constant value. In this lab assignment DC will refer to a constant voltage or current.

  • Switch Mode Power Supplies and Their Magnetics Tutorial
    Datatronic Switch Mode Power Supplies and their Magnetics Many factors must be considered by designers when choosing the magnetic components required in today’s electronic power supplies DATATRONIC DISTRIBUTION, INC. Datatronic In today’s day and age the most often used topology for electronic power supplies is that of the Switch Mode Power Supply (SMPS), which is a major user of magnetics. In some applications the “older type” linear supplies are still used, but in the early 70’s SMPS came into being spurred by the development of faster switching transistors. This facilitated the use of much smaller magnetic components and greater efficiencies. DATATRONIC DISTRIBUTION, INC. Datatronic SMPS and their General Magnetic Usage In general, there are four different types of magnetic components that are needed for the typical SMPS. They include the Output Transformer, usually the most noticeable because of its size compared to the others, the Output Inductors, the Input Inductors and the Current Sense Transformer, each with its own important function. DATATRONIC DISTRIBUTION, INC. Datatronic SMPS and their General Magnetic Usage 1.The Output Transformer or “Main” Transformer takes the input voltage that is supplied to its primary winding and then transforms the input voltage to one or more voltages that are the output of the secondary winding or windings. 2. The Output Inductors are used to filter the output voltage so that the load “sees” a filtered DC voltage. DATATRONIC DISTRIBUTION, INC. Datatronic SMPS and their General Magnetic Usage 3. The Input Inductors filter out the noise generated by the switching transistors so that this noise isn’t emitted back to the source.

Selecting the Best Capacitor for Your Motor Drive Application Aluminum capacitors are often used as DC link capacitors in motor drives, both in 1-phase and 3-phase designs. The aluminum capacitor is used as an energy buffer to ensure stable operation of the switch mode inverter driving the motor. The aluminum capacitor also functions as a filter to prevent high-frequency components from the switch mode inverter from polluting the mains voltage. The key selection criterion for the aluminum capacitor is the required ripple current. The ripple current consists of two components, a low-frequency ripple (50 Hz to 200 Hz) from the input and a high-frequency component from the inverter, typically 8 kHz to 20 kHz.

  • AN-500: Depletion-Mode Power Mosfets and Applications
    INTEGRATED CIRCUITS DIVISION Application Note AN-500 Depletion-Mode Power MOSFETs and Applications AN-500-R03 www.ixysic.com 1 INTEGRATED CIRCUITS DIVISION AN-500 1 Introduction Applications like constant current sources, solid state relays, and high voltage DC lines in power systems require N-channel depletion-mode power MOSFETs that operate as normally-on switches when the gate-to-source voltage is zero (VGS=0V). This paper will describe IXYS IC Division’s latest N-channel, depletion-mode, power MOSFETs and their application advantages to help designers to select these devices in many industrial applications. Figure 1 N-Channel Depletion-Mode MOSFET D ID + G V + DS IG V - GS I - S S A circuit symbol for an N-channel depletion-mode power MOSFET is given in Figure 1. The terminals are labeled as G (gate), S (source) and D (drain). IXYS IC Division depletion-mode power MOSFETs are built with a structure called vertical double-diffused MOSFET, or DMOSFET, and have better performance characteristics when compared to other depletion-mode power MOSFETs on the market such as high VDSX, high current, and high forward biased safe operating area (FBSOA). Figure 2 shows a typical drain current characteristic, ID, versus the drain-to-source voltage, VDS, which is called the output characteristic. It’s a similar plot to that of an N-channel enhancement mode power MOSFET except that it has current lines at VGS equal to -2V, -1.5V, -1V, and 0V. Figure 2 CPC3710 - MOSFET Output Characteristics Output Characteristics (TA=25ºC) 300 270 VGS=0.0V 240 210 V =-1.0V 180 GS 150 (mA) D I 120 V =-1.5V 90 GS 60 V =-2.0V 30 GS 0 0123456 VDS (V) The on-state drain current, IDSS, a parameter defined in the datasheet, is the current that flows between the drain and the source at a particular drain-to-source voltage (VDS), when the gate-to-source voltage (VGS) is zero (or short-circuited).

  • EXP4: Rectifiers
    EXP4: Rectifiers OBJECTIVES. The general objective of this experiment is for you to become familiar with the response of a diode in a circuit, whether the circuit is supplied with a DC, AC or AC-DC voltage. In this part we will also see how to couple AC and DC sources, and finally we will illustrate the use of diodes in rectifying circuits. INTRODUCTION AND TEST CIRCUITS. The circuits we will be studying are the basic limiting circuit, half-wave and full-wave rectifiers. We will be doing the analysis of the circuits using aproximation, such as assuming we know the diodes’ voltage Vf . Also we will make use of the graphical method to find the voltage and current in the diode. We will run a bias analysis using PSpice which is the same as using an iterative method. And finally we will measure in lab the actual voltage and current values. That way we will be able to evaluate the accuracy of the different methods. We will also get the transfer characteristic, and use it to predict the output waveform for a given input. We will check our estimate using PSpice and in lab. For theory on the behavior of the circuits we will be studying please refer to the textbook or some book that covers the topics, limiting and rectifying circuits. PREPARATION. For the first two circuits, the limiting and the half-wave rectifier we will do the analysis using different methods. If you are not familiar with any of these methods please refer to the textbook or some book that covers this topic.
