OPEN-ENDED CONTROL CIRCUIT FOR ELECTRICAL APPARATUS

摘要

An AC machine control system for an AC machine (102) (motor, generator, transformer, etc.) having open-ended windings, the control system comprising a drive circuit (100) configured to transfer AC power between a first set of voltages and each end of the open-ended windings without the use of a substantial energy storage device, while eliminating common mode voltage and/or injecting zero sequence voltages.
