Abstract :
A novel single stage, high-power factor three-phase power supply which consists of a high frequency, line-side interphase transformer and a high switching frequency, isolated, DC-DC current source push-pull power converter is presented. Besides the high power factor, it presents soft switching both at turn-on and turn-off of the power and auxiliary switches. The high power factor and low harmonic content are reached by means of a line interphase transformer which is in turn switched at a high frequency by means of a push-pull power converter. The main analytical equations, simulation and experimental results are presented
