AUXILIARY CIRCUIT FOR USE WITH THREE-PHASE DRIVE WITH CURRENT SOURCE INVERTER POWERING A SINGLE-PHASE LOAD

摘要

The present invention is directed to an auxiliary circuit for reducing low order current harmonics in a three-phase drive system driving a single-phase load, the three-phase drive system including a three-phase source voltage connected to a rectifier system connected to a DC link choke inductor connected to a three-phase current source inverter system.
