一种用于燃料电池应用的宽输入电压范围单向谐振开关电容变换器

A multi-phase high voltage gain resonant switched capacitor converter (SCC) that provides soft switching conditions for all power semiconductor devices above and below the resonant frequency. Its output voltage can be regulated by the frequency modulation technique across wide input voltage and load variation ranges by a small switching frequency variation. Symmetrical structure, small input-output filters, compact passive components, low switching losses and reduced EMI noise, input-output common ground, simple control circuit and high voltage gain make the proposed converter suitable for various applications.
