Abstract: A method of converting power includes receiving alternating current (AC) at the first phase leg set of a power conversion system having first and second phase legs sets connected by direct current (DC) leads. The first phase leg set rectifies the received AC power into DC power by switching outer switches of the first phase leg set into an off state. The DC lead conveys the DC power from the first phase leg set to the second phase leg set. The second phase leg set inverts the DC power into AC power.

Abstract: A three phase step-up autotransformer construction is discussed herein. The passive 12-pulse AC-DC converter offers simplicity, high reliability and low cost solution to AC-DC power conversion. The autotransformer is a component of the passive 12-pulse AC-DC converter. The autotransformer converts three-phase AC power into six-phase AC power. With appropriate vector design, the autotransformer may be configured to draw a near sinusoidal 12-pulse current waveform from the three-phase voltage source. The six-phase output may be configured to drive a rectifier (non-linear) load.
