Abstract :
Two types of three-phase resonant pulsewidth-modulation (PWM) controlled DC-DC converters are presented. It is shown that the combination of resonant and PWM control methods can be used to tightly regulate the output voltage from no load to full load at constant switching frequency and with low switching losses. It is also shown that both topologies exhibit zero voltage switching in continuous conduction mode. In discontinuous mode the turn-on losses are very similar to PWM converters. Relevant input and output current waveforms and component design ratings are derived. Key predicted results are verified experimentally on a laboratory prototype unit
