Abstract :
The design and breadboard implementation of a single-switch three-phase high power factor multi-resonant rectifier delivering 147 V (DC) at 6 kW from a 3φ 240 V (L-L, rms) AC input is described. This rectifier has continuous input and output currents. By the use of a multi-resonant scheme, the transistor operates with zero current switching and the diodes operate with zero voltage switching. This paper focuses on the design, implementation, and performance of the rectifier. High quality input current waveforms at nearly unity power factor, wide load range, and low stresses on the semiconductor devices are attained. The total harmonic distortion (THD) of the line current is less than 5% and the system efficiency is about 94% at full load
