Implementation of single-phase boost power factor correction circuits in three-phase applications

A three-phase rectifier employing three single-phase boost power factor correction circuits is analyzed. Each converter operates in the continuous conduction mode (CCM), which allows a high power factor and a small EMI filter. Current sharing is ensured by a common voltage loop driving the individual current loops of the three converters. A suitable circuit arrangement is devised to limit phase interaction. The zero-voltage-transition technique (ZVT) is successfully applied to each converter in order to obtain zero turn-on losses and soft turn-off of the freewheeling diodes. Results of a 1800 W, 100 kHz experimental prototype are reported, which confirm the theoretical forecasts.<<ETX>>
