A parallel LLC series resonant converter with output voltage doubler is presented in this paper. The interleaved pulse-width modulation (PWM) technique is adopted to reduce the ripple current on input and output capacitors. The capacitance of input and output capacitors can be reduced. The high current stress drawback of conventional LLC resonant converter is overcome by the proposed converter. Thus...
A soft switching converter with parallel-connected full-wave rectifiers is presented. In the proposed converter, the primary windings of two transformers are connected in series. Two full-wave rectifiers with ripple current cancellation are connected in parallel at the output side to reduce the current stress of the secondary winding of transformer. The clamp circuit based on an auxiliary switch and...

This paper presents the system analysis and circuit implementation of a zero voltage switching (ZVS) half-bridge converter with current doubler rectifier. The asymmetrical pulse-width modulation technique is used in the adopted power converter to regulate the DC output voltage and improve the duty cycle utilization. The transformer leakage inductance and the output capacitance of power switches are...
