The single switch and the input diode bridge in this rectifier operates with zero current switching while the DC-side diode operates with zero voltage switching. The semiconductor stresses are constant and are independent of load current variations. A multi-resonant scheme is used to achieve this property. Line current waveforms of low harmonic content are obtained naturally by these rectifiers. Simulation and experimental results are supplied to confirm the validity of the proposed concept
