Power devices IGBTs

At present, modern power components such as GTO (Gated Transistor On/Off device), IGBT (Isolated Gate Bipolar Transistor), Power Mosfet (Metal Oxide Field Effect Transistor), and high voltage capacitors are easily commercially available and perfectly adequate to realize the energy storage... 

In this chapter, two types of power devices will be discussed, which use CMP in their manufacturing flow, the power MOSFET and IGBT. They are designed to handle voltages up to 1000 V or even larger and can control currents up to several hundred amperes. Both types of devices are fabricated in large scale and can be found in...

This is applicable to thyristor (SCR) circuits to protect all the semiconductor devices used in the switching circuit, such as diodes (also power diodes) or IGBTs, in addition to SCRs. The same protection can be applied to all the semiconductor circuits likely to experience high dv/di. 

For low-power applications, the devices of choice are the MOSFET, the IGBT, and the BJT. For applications up to 1 kV, the MOSFET is the device of choice because it is a voltage-control device and has a fast switching speed. For applications ranging in voltage from 1 kV up to 4 kV, the IGBT is most often used. The thyristor and the GTO are used for voltages over 4 kV.

Zero-current-transition PWM converters (Hua, Leu, and Lee, 1992) Figure 10.91 shows an example of zero-current transition boost converter. This approach is useful in high power converters when insulated gate bipolar transistors (IGBTs) or bipolar transistors are used as the switching devices. 

A simplified schematic of the APLC power circuitry is given in Fig. 10.174. The DC bus (Vac) is the energy storage device that supplies the power required for voltage compensation and current injection. The parallel filter serves two purposes. First, the IGBTs in this portion of the APLC keep the DC link capacitor...
