Given the wide availability of high voltage power IGBTs and MOSFETs with breaking voltage ratings of 500 to 800 V, designers often face the challenge of selecting an IGBT or MOSFET for a given application and a set of operating conditions. In the case of three-phase variable speed motor drives in the range of nominal powers from 300 W to 5 kW, using a DC bus voltage in the range of 300 to 400 V and typically implemented by a topology of six switches, The IGBT 600 to 650 V (co-packaged with an anti-parallel fast recovery diode) have traditionally been the preferred device from a global performance perspective. However, with the availability of high switching speed.
