All rights reserved. An Altair Company Description of Boost Converter In a boost converter, the output voltage is greater than the input voltage, hence the name “boost”. The function of boost converter can be divided into two modes, Mode 1 and Mode 2. Mode 1 begins when Switch “ S ” is ON at time t=0. The input current rises and flows through inductor L and Switch. Mode 2 begins when Switch “ S ” is OFF at time t = t1. The input current now flows through L, C, load, and diode . The inductor current falls until the next cycle. The energy stored in inductor L flows through the load. By the proper design of the inductor and the capacitor values and the duty cycle of the triggering pulse with the suitable switching frequency, gives the output from the converter. • ACTIVATE solidThinking © 2017 solidThinking, Inc.

The main advantages of this topology are: simple structure on the converter’s power stage; a wide range of the output voltage, capable of supporting contemporary vehicles’ on-board battery packs; eﬃciency; and power density accepted to be high enough for such a class of hard-switched converters. A precise estimation of the loss, dissipated in the converter’s basic modes of operation Buck, Boost, and Buck-Boost is presented. The analysis shows an approach of loss minimization, based on switching frequency reduction during the Buck-Boost operation mode. Such a technique guarantees stable thermal characteristics during the entire operation, i.e., battery charge cycle.

In order to convert AC-DC we need a bridge rectifier and boost converter for step up the DC output voltage to meet the load demand. This two- stage conversion process increases the converter cost and reduces the efficiency of converter due to presence of more no. of semi conductor devices. The proposed converter consists of a boost converter in parallel with a buck–boost converter. Boost converter operated in the positive half cycle and buck-boost converter in the negative half cycle. As a result we obtain a high DC output voltage from a low AC input voltage in single stage conversion. The proposed converter has been designed by using MATLAB. Keywords: AC-DC converter, boost converter, buck-boost converter. I. INTRODUCTION Power electronics may be defined as the subject of applications of solid state power semiconductor devices (Thyristors) for the control and conversion of electric power.

How to Select a Proper Inductor for Low Power Boost Converter
Application Report SLVA797–June 2016 How to Select a Proper Inductor for Low Power Boost Converter Jasper Li ............................................................................................. Boost Converter Solution / ALPS 1 Introduction Traditionally, the inductor value of a boost converter is selected through the inductor current ripple. The average input current IL(DC_MAX) of the inductor is calculated using Equation 1. Then the inductance can be [1-2] calculated using Equation 2. It is suggested that the ∆IL(P-P) should be 20%~40% of IL(DC_MAX) . V x I = OUT OUT(MAX) IL(DC_MAX) VIN(TYP) x η (1) Where: • VOUT: output voltage of the boost converter. • IOUT(MAX): the maximum output current. • VIN(TYP): typical input voltage. • ƞ: the efficiency of the boost converter. V x() V+ V - V L = IN OUT D IN ΔIL(PP)- xf SW x() V OUT+ V D (2) Where: • ƒSW: the switching frequency of the boost converter. • VD: Forward voltage of the rectify diode or the synchronous MOSFET in on-state. However, the suggestion of the 20%~40% current ripple ratio does not take in account the package size of inductor. At the small output current condition, following the suggestion may result in large inductor that is not applicable in a real circuit. Actually, the suggestion is only the start-point or reference for an inductor selection. It is not the only factor, or even not an important factor to determine the inductance in the low power application of a boost converter. Taking TPS61046 as an example, this application note proposes a process to select an inductor in the low power application.

DC/DC Converter Output Capacitor Benchmark
DC/DC Converter Output Capacitor Benchmark R. Šponar, R. Faltus, M. Jáně, Z. Flegr, T. Zedníček AVX Czech Republic s.r.o., Dvorakova 328, 563 01 Lanskroun, Czech Republic email: [email protected] Abstract Switched-mode power supplies (SMPS) are commonly found in many electronic systems. Important SMPS requirements are a stable output voltage with load current, good temperature stability, low ripple voltage and high overall efficiency. If the electronic system in question is to be portable, small size and light weight are also important considerations. A key component in switching power systems is the output capacitor – used to store the charge and for smoothing - therefore its careful selection plays a vital role in determining the overall parameters of the power supply. Different capacitor technologies – tantalum, ceramic MLCC, niobium oxide (NbO) and aluminium - are suitable to meet different electrical requirements. This paper presents the results of an output capacitor benchmark study used in a step-down DC/DC converter design, based on a well-used control IC (Maxim’s MAX 1537 – Ref.1) with a 6-24V input voltage range and two separate voltage outputs of 3.3 and 5V. The behaviour of different output capacitor technologies was evaluated by measuring the output ripple voltage. Defined fixed load and fixed switching frequency settings were used for all measurements. Introduction The selection of a suitable output capacitor plays an important part in the design of switching voltage converters. “Some 99 percent of so-called ‘design’ problems associated with linear and switching regulators can be traced directly to the improper use of capacitors”, states the National Semiconductor IC Power Handbook (Ref.2).

The proposed converter is composed of a three-level flying-capacitor switching cell and an integrated LC2D output network. The LC2D output network enhances the voltage gain of the converter and reduces the voltage stress on the power switches. The proposed converter is a good candidate to interface fuel cells to the dc-link bus of the three-phase inverter of an electric vehicle (EV). A full steady-state analysis of the proposed converter in the continuous conduction mode (CCM) is given in this paper. A 1.2 kW scaled-down laboratory setup was built using gallium nitride (GaN) transistors and silicon carbide (SiC) diodes to verify the feasibility of the proposed converter. Keywords: boost converter; multilevel; wide-bandgap; GaN; SiC; canonical switching cell; flying capacitor; renewable energy; fuel cells; electric vehicles 1. Introduction There is a growing global interest in reducing greenhouse gases by developing new clean energy technologies that address the challenges associated with the increasing penetration of renewable energy systems and the need to reduce fossil fuel consumption.

Received: 21 November 2018; Accepted: 21 February 2019; Published: 6 March 2019 Abstract: This work deals with the novel application of the sliding mode (discontinuous) output regulation theory to a nonlinear electrical circuit, the so-called boost power converter. This theory has excelled due to the fact that trajectory tracking plays a central role. The control of a boost power converter for the output tracking of a DC biased sinusoidal signal is a challenging problem for control engineers. The main difﬁculties are the computation of a proper reference signal for the inductor current, and the stabilization of the inductor current dynamics or to guarantee the correct output tracking of the capacitor voltage. With the application of the discontinuous output regulation these problems are solved in this work. Simulations and real time experiments were carried out with an unknown variation of the DC input voltage, where the good output tracking of the capacitor voltage was veriﬁed along with the stabilization of the inductor current.

Application Report SLVA372C–November 2009–Revised January 2014 Basic Calculation of a Boost Converter's Power Stage Brigitte Hauke ......................................................................................... Low Power DC/DC Application ABSTRACT This application note gives the equations to calculate the power stage of a boost converter built with an IC with integrated switch and operating in continuous conduction mode. It is not intended to give details on the functionality of a boost converter (see Reference 1) or how to compensate a converter. See the references at the end of this document if more detail is needed. For the equations without description, See section 8. 1 Basic Configuration of a Boost Converter Figure 1 shows the basic configuration of a boost converter where the switch is integrated in the used IC. Often lower power converters have the diode replaced by a second switch integrated into the converter. If this is the case, all equations in this document apply besides the power dissipation equation of the diode. D IIN L IOUT V IN C VOUT CIN SW OUT Figure 1.
