Abstract

In modern pulsed power systems, often, fast solidstate
switches likeMOSFETs and insulated gate bipolar transistor
(IGBT) modules are used to generate short high power pulses. In
order to increase the pulsed power, solid-state switches have to be
connected in series or in parallel. ....etc

Abstract-
In this paper, a new complementary gate driver for power metal-oxide semiconductor field-effect transistors and in sulated gate bipolar transistors is presented based on the use of a piezoelectric transformer (PT). This type of transformer has a high integration capability. Its design is based on a multilayer struc ture working in the second thickness resonance mode. A new de sign method has been used based on an analytical Mason model in order to optimize the efficiency, the available power at the trans former secondary ends, and ....etc

working of igbt with flash animation

What is an IGBT?
An IGBT, or insulated gate bipolar transistor, is a solid state device (with no moving parts). It is a switch that is used in order to allow power flow in the On state and to stop power flow when it is in the Off state. An IGBT works by applying voltage to a semiconductor component, therefore changing its properties to block or create an electrical path.
Types of IGBTs

There are many different kinds of IGBTs. At Future Electronics we stock many of the most common types categorized by Turn- ....etc

Silicon carbide devices have several advantages, including high blocking voltage, lower conduction losses, and lower switching losses, when compared to silicon-based devices. This paper demonstrates high power and high frequency operation of the SiC MOSFETs compared to conventional Si IGBT with a similar power rating. The commercial SiC MOSFET QJD1210007 (1200V/100A) from POWEREX and Si IGBT CM100TF-24H (1200V/100A) from Mitsubishi were used in this study. PSCAD and Matlab/Simulink models were used to analyze the power losses of the devices. Th ....etc

Abstract
High Voltage IGBT (HVIGBT) modules with high performance in the areas of low power loss and high reliability are required for high power applications such as traction, large industrial motor drives, and medium voltage converters. Unfortunately, these performances are often in reciprocal relationship. In order to achieve a higher performance with optimized tradeoffs at the 3.3kV level, a new IGBT and Free wheeling Diode (FWD) chip set was developed. This paper describes the optimization of the chip design ....etc

ppt speed control dc motor using igbt

INTRODUCTION

Developments of high performance motor drives are very essential for industrial applications. A high performance motor drive system must have good dynamic speed command tracking and load regulating response. DC motors provide excellent control of speed for acceleration and deceleration. The power supply of a DC motor connects directly to the field of the motor which allows for precise voltage control, and is necessary for speed and torque control applications. DC drives, because of their simp ....etc

MODELLING AND SIMULATION OF SOFT-SWITCHING DC/DC CONVERTER WITH HIGH VOLTAGE GAIN



INTRODUCTION

Recently, the demand for dc/dc converters with high
voltage gain has increased. The energy shortage and
atmosphere pollution have led to more researches on the
renewable and green energy sources such as the solar
arrays and the fuel cells. Moreover, the power systems
based on battery sources and super capacitors have been
increased. Unfortunately, the output voltages of these
sources are relativel ....etc
