Research on Soft-Switched Single-Switch Three-Phase Rectifier with Power Factor Correction
Abstract：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 topol-ogy 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.
