Analysis, design and implementation of a high-voltage gain DC-DC converter

摘要: An interleaved DC-DC converter with soft switching technique is presented. There are two modules in the adopted circuit to share load power. Since pulse-width modulation PWM control modules, ripple currents at input and output sides naturally reduced. Therefore capacitances can be In each module, a conventional boost voltage doubler configuration coupled inductor connected series side achieve high step-up conversion ratio. Active snubber parallel limit stress on active switch release energy stored leakage magnetizing inductances. asymmetrical used switches, inductance capacitance of switches resonant transition interval. Thus, both turned zero switching. The secondary transformer current turn-off for rectifier diodes. Therefore, reverse recovery losses fast diodes Finally, experiments based laboratory prototype rated 400W presented verify effectiveness proposed converter. Copyright © 2012 John Wiley & Sons, Ltd.
