Abstract :
A new class of single-switch low harmonic boost-type rectifiers suitable for both single and three phase applications are introduced in this paper. All the semiconductors in these rectifiers operates with zero-voltage switching and clamped voltage (ZVS-CV) with minimum voltage stress while the DC-side diode turns-off at zero-current. Hence, the switch turn-on loss and noise are sufficiently reduced. 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 for a boost-type rectifier are presented
