Zero current transition (ZCT) topology of the single switch three phase boost power factor correction (PFC) rectifier is proposed. The soft transition is achieved with low power auxiliary circuit employing an additional switch. Operation of the ZCT topology is analyzed in detail, design guidelines are provided. The results are verified on 1 kW, 50 kHz, simulated ZCT rectifier with IGBTs. Total harmonic distortion below 9% is obtained.
