  • Fundamentals of MOSFET and IGBT Gate Driver Circuits
    Application Report SLUA618A–March 2017–Revised October 2018 Fundamentals of MOSFET and IGBT Gate Driver Circuits Laszlo Balogh ABSTRACT The main purpose of this application report is to demonstrate a systematic approach to design high performance gate drive circuits for high speed switching applications. It is an informative collection of topics offering a “one-stop-shopping” to solve the most common design challenges. Therefore, it should be of interest to power electronics engineers at all levels of experience. The most popular circuit solutions and their performance are analyzed, including the effect of parasitic components, transient and extreme operating conditions. The discussion builds from simple to more complex problems starting with an overview of MOSFET technology and switching operation. Design procedure for ground referenced and high side gate drive circuits, AC coupled and transformer isolated solutions are described in great details. A special section deals with the gate drive requirements of the MOSFETs in synchronous rectifier applications. For more information, see the Overview for MOSFET and IGBT Gate Drivers product page. Several, step-by-step numerical design examples complement the application report.

  • Capacitor and Inductors
    Capacitors and inductors We continue with our analysis of linear circuits by introducing two new passive and linear elements: the capacitor and the inductor. All the methods developed so far for the analysis of linear resistive circuits are applicable to circuits that contain capacitors and inductors. Unlike the resistor which dissipates energy, ideal capacitors and inductors store energy rather than dissipating it. Capacitor: In both digital and analog electronic circuits a capacitor is a fundamental element. It enables the filtering of signals and it provides a fundamental memory element. The capacitor is an element that stores energy in an electric field. The circuit symbol and associated electrical variables for the capacitor is shown on Figure 1. i C + v - Figure 1. Circuit symbol for capacitor The capacitor may be modeled as two conducting plates separated by a dielectric as shown on Figure 2. When a voltage v is applied across the plates, a charge +q accumulates on one plate and a charge –q on the other. insulator plate of area A q+ - and thickness s + - E + - + - q v s d Figure 2.

    Publication Since 2012 | ISSN: 2321-9939 | ©IJEDR 2020 Year 2020, Volume 8, Issue 2 What is Future Scope of PCB Fabrication & Manufacturing in Industries 1Manish Ranjan, 2Sumit Kumar Singh 1Student, 2Student G L Bajaj Group of Institutions, Mathura _____________________________________________________________________________________________________ Abstract - Printed circuit board (PCB) is base of any electronics/electrical equipment. A PCB provides the connectivity to the electronic component such as resistor, capacitor, coils, pots, diodes, FET, transistor, ICs, transformer etc. to form a complete electronic circuit. In the present scenario, the existence of electronics equipment’s cannot be imagined without a PCB. The PCBs are not only providing the connectivity among the electronic components but also reduces the size and increases the efficiency of the electronic equipment. Broadly the PCBs may be divided in two categories i.e. single layer PCBs and multi-layer PCBs. One can easily find the contribution of electronic industries in each and every field of our daily life i.e. entertainment, communication, education, R&D, Public Services, Defence, Transport, Agriculture, health care services etc. With the growing demand of electronic equipment’s/appliances in every sphere of human beings the electronic industry is growing up with a very fast rate. Similarly, the demand of micro servicing industries such as assembling/mounting of electronic component on PCBs to meet the requirement of the small/medium/large scale electronic industries is also increasing. This Paper Discuss what is the future scope of PCB board fabrication and manufacturing in industries. Our Conclusion show that the PCB manufacturing and fabrication is very fast growth in future. keywords - PCB board, fabrication, manufacturing, PCB design industry segment, future scope, growth rate, _____________________________________________________________________________________________________ 1.
