Abstract :
A new three-phase high-quality boost rectifier system is introduced in this paper. The single switch and input-diode bridge in this rectifier operate with zero-current switching (ZCS) while the DC-side diode operates with zero-voltage switching (ZVS). The semiconductor stresses are constant and independent of load-current variations. A multiresonant 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
