Constant frequency PWM capacitor voltage-clamped series resonant power supply

摘要: The authors propose a capacitor-voltage-clamped series-resonant converter, regulated at constant frequency by pulse-width modulation (PWM), that is suitable for an offline isolated multiple output power supply. principle of operation, theoretical analysis, simulation, design procedure, and example are provided, along with experimental results. validity the analysis main properties proposed converter were demonstrated in laboratory, construction supply rated 12 V/16 A operating 100 kHz. technique significantly reduces RMS value current through transistors, size filter capacitor, improves dynamic response. >
