Abstract

The above schematic represents a breadboard implementation of a scheme utilizing three "boost regulators" to obtain a source of DC power from a three-phase AC power distribution without the usual input current waveform distortion. Breadboard measurements indicate true unity power factor and a minimum 98% reduction in the amplitude of line frequency harmonics over a conventional bridge rectifier.
