The drive circuit of the IGBT must have two functions: one is to achieve electrical isolation between the control circuit and the gate of the driven IGBT; the other is to provide a suitable gate drive pulse. There are many driving circuits for IGBTs, and the driving circuit for discrete components is simple and inexpensive. […]

Temperature control is one of the key factors for the effective operation of MOSFET or IGBT module. Although some MOSFETs are equipped with an internal temperature sensor (body diode), other methods can also be used to monitor temperature. The semiconductor silicon PTC thermistor can perform current control well, or the platinum-based or niobium-based (RTD) resistance […]
