ABSTRACT:
A high voltage, single-stage variable speed motor power supply utilizes direct AC-to-AC converters that do not have any intermediate DC link, along with a multi-level, multi-phase, multi-circuit variable speed motor drive and a motor in which a stator is wound with a number of multi-phase circuits. Each multi-phase circuit includes semiconductor switches arranged in drive switch pairs which are operated to produce an effective DC supply with the switches being controlled so that the most positive line-to-line source voltage is utilized for the inversion process.
