IGBT transistor VS MOSFET transistor
What is the difference between MOSFETs and IGBTs?
There are three major types of transistors: bipolar transistors, MOSFETs, and IGBTs. The following table compares the performance and characteristics of these transistors. Bipolar transistors are now hardly ever used for power electronics and switching applications because of the need for drive and protection circuits and slow switching speed. Instead, MOSFETs and IGBTs are selectively used according to the required characteristics. The figure given alongside shows the on-state voltage characteristics of a 30-A IGBT and a 31-A super-junction MOSFET (SJMOS).
In the low-current region, the MOSFET exhibits a lower on-state voltage than the IGBT. However, in the high-current region, the IGBT exhibits lower on-state voltage than the MOSFET, particularly at high temperature. IGBTs are commonly used at a switching frequency lower than 20 kHz because they exhibit higher switching loss than unipolar MOSFETs.
