The chapter points out that sequential switching is not only applicable to IGBT modules with integrated diodes mounted closely on a heat sink, but also to complete industrial standard two‐level voltage source inverters (VSIs). Thus, the power capability and the overall switching frequency of these products can be increased by using several of them in parallel with sequential switching. Using ...

This chapter aims to give sufficient knowledge of how electric power is converted using electronic power converters, in order to facilitate the study of electric drives. Furthermore, it presents how inverters operate to allow power to be fed into grids from low power power plants such as small photovoltaic generators. A concise description of the behaviour of the devices, as well as an introduction to approximations in such a way that they can be analysed using the linear circuit concepts. Rectifiers are devices that convert AC power into DC without affecting (if we disregard inner power losses) the transferred power. This concept is illustrated, showing single- phase and three-phase rectifiers.
The chapter points out that sequential switching is not only applicable to IGBT modules with integrated diodes mounted closely on a heat sink, but also to complete industrial standard two‐level voltage source inverters (VSIs). Thus, the power capability and the overall switching frequency of these products can be increased by using several of them in parallel with sequential switching. Using this approach, a novel electrical test bench for drive inverters can be set up with a minimum effort on design and development. This provides an alternative for manufacturers of drive inverters to test their complete product range under real power levels without the requirement for a multitude of real machines.The discussion provided in the chapter proves that the so called virtual machine (VM) is a Hardware‐in‐the‐Loop system allowing an inverter to be tested at real power levels without the need for installing and operating real machines. The VM has the same characteristics as a real induction motor or even a synchronous motor. Different machines and their respective load conditions can be emulated by software, which means that the drive inverter under test can operate in its normal mode (as usual). No modification has to be done to the inverter or to the control unit.
Two approaches of forming IGBTs with shallow emitter ballast have been investigated in this study. These designs are compared in terms of their layout scheme, fabrication steps and device performance. This shallow emitter ballast provides the necessary trade-off between on-state and ruggedness of IGBTs. Using this concept 600 V IGBTs with an on-voltage of /spl sim/1.6 V@100 A/cm/sup 2/, turn-off energy of /spl sim/30 /spl mu/J/A, short-circuit time of /spl sim/27 /spl mu/s, and a maximum UIS energy of /spl sim/13.4 mJ/A have been fabricated.
Local heating effects are simulated for both types of transistor, by solving the current continuity and Poisson equation fully in 2-Dimensions and calculating local heating from the resulting Current Density and Electric Field. The effect of Generation-Recombination heating is also included and compared with the case where this is not significant. Finally this heat-source term is used in the solution of the Heat Equation in order to find the steady state temperature distribution. It is found that strong local heating effects occur in both devices with apparent cooling occurring in some regions where recombination has been ignored, which may have a beneficial effect on the locally heated regions.<<ETX>>
The drive circuit requirements of the OGBT are explained with the aid of an analytical model. This model can be used to describe the turn-on and turn-off, gate and anode, current and voltage waveforms for general external drive, load, and feedback circuits. It is shown that nonquasi-static effects limit the influence of the drive circuit on the time rate-of-change of the anode voltage. Model results are compared with measured turn-on and turn-off waveforms for different drive, load, and feedback circuits and for different IGBT base lifetimes. The effective output capacitance of the IGBT at turn-off is several orders of magnitude larger than that of the structurally equivalent power MOSFET and depends upon the device base lifetime because the base charge at turn-off depends upon the device base lifetime. However, the gate drain feedback capacitance is unchanged from the value for the structurally equivalent power MOSFET. Thus, the minimum gate resistance that influences the anode voltage rate-of-rise at turn-off is several orders of magnitude larger than that for the power MOSFET and varies with device base lifetime.<<ETX>>
This paper reports the internal dynamics of insulated gate bipolar transistors (IGBT's) under short-circuit switching conditions. Short-circuit performance of IGBT's has been studied in detail with the aid of extensive measurements and numerical simulations. An advanced two-dimensional (2-D) mixed device and circuit simulator that incorporates the self-heating mechanism has been employed to examine IGBT behavior under short-circuit stress. Latch-up free punchthrough IGBT has been examined. It is shown that hot-spot generation due to current crowding and impact ionization is the cause of breakdown of an IGBT under short-circuit switching.
IGBTs with blocking voltage values of 600 V, 1200 V and 1600 V are available for several applications. In traction applications, 600 V and 750 V DC mains are widely distributed. The 1500 V DC mains becomes more and more of interest in Asia, South America and in Europe. Industrial applications have AC mains of 360 V, 500 V, 660 V, etc. While 1600 V IGBT-modules meet the requirements in 750 V DC mains application, there is no alternative to GTOs for higher voltages. This paper describes a 3300 V IGBT-module for application in diesel- electric trains, high speed trains and underground/downtown trains, the latter operating directly on the 1500 V DC mains with motor power ratings up to 1.5 MW. Three-level inverters with IGBTs allow operation at 3000 V DC mains or at 2200 V AC line voltages in industrial power converters which is widely distributed in North America.
