A novel high efficiency PWM ZVS full-bridge dc-dc converter is presented. A half-bridge LLC resonant circuit which operates at a specific resonant frequency assists the PSFB dc-dc converter achieving ZVS of the lagging-leg switches from zero to full load. The output voltage of LLC resonant circuit is applied to the leakage inductance during the freewheeling phases. The primary circulating current...
A novel control strategy is proposed to improve the efficiency and to realize safe soft commutation of the high-frequency inverter which is composed of full-bridge, high-frequency transformer and cycloconverter. Through the novel control strategy the full-bridge switches can achieve almost full-range zero-voltage switching on, and the cycloconverter switches can achieve full-range zero-current switching...
A double PWM plus double phase shift (DPDPS) control with equal duty cycles is proposed for current-fed dualactive bridge (DAB) bidirectional DC-DC converters with low and wide voltage range. With these, the circulating current during the non-power transfer stage can be minimized. The mode analysis of the current-fed bidirectional DC-DC converter using the proposed control strategy is given. The root-mean-square...
