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.
