Abstract

Trends in modern motor designs require the power converter to satisfy stringent requirements. A few of the recently proposed quasi-resonant inverters have the capability to reach the performance levels required to drive these motors directly. A comparative evaluation of these inverter topologies is presented, with the conventional hard switched inverter as the base. All these inverters represent performance and size advantages compared to a conventional hard switched inverter. A preliminary reliability analysis reveals that the new topologies have somewhat smaller MTBF (mean time between failures) than the conventional hard switched inverter
