A new, three-phase, two-switch, power-factorcorrection (PFC) rectifier that can achieve less than 5% inputcurrent total harmonic distortion (THD) and features zerovoltage switching (ZVS) of all the switches over the entire input-voltage and load ranges is introduced. The proposed rectifier also offers automatic voltage balancing across the two output capacitors connected in series, which makes it possible to use downstream converters designed with lower-voltagerated component that offer better

The performance of the proposed rectifier was evaluated on a 2.8-kW prototype with a 780-V output that was designed to operate in 340-520-V L-L, RMS input-voltage range.
