Abstract :
The weight and volume of power supply devices can be further reduced, and noise can be decreased by using a three-phase converter in combination with a high-frequency AC link. A new control method of pulse density modulation (PDM) is used in the converters. The operation principle of the circuit is explained in detail. The expressions of the phase voltage and current and harmonics analysis are described separately. The simulation results prove the analysis to be true.
