This paper proposes an improved method to describe power losses in IGBT converters. This method includes dependency of voltage, current and temperature, and it could be fast and accurate. Since the relative higher converter dissipation is one of the main barriers in high power applications, it is further compared the MVA rated three-phase IGBT converter's loss rates under different operating frequency, then discusses the suitable SPWM frequency for high power applications.
