Abstract

A three-level ZCT(Zero Current Transition) IGBT inverter is presented for high power IGBT inverters. The concept of ZCT for the conventional boost converter is extended to the three-level inverter. Moreover, in order to improve the reliability of inverter, midpoint charge balance problem of the three-level inverter is analyzed with respect 150kw, 20kHz prototype are presented to verify the principle of ZCT Operation.
