基于双谐振核的混合控制策略升降压开关电容变换器及其在宽输出电压应用中的频率范围缩减研究

Wide voltage range converters are significant for photovoltaic power generation system, battery charging, and auxiliary power source, etc. Resonant converter has been preferred topology for these applications, however, some demerits exist: 1) difficult to realize wide voltage gain range and low circulating current losses; 2) widely regulated switching frequency to adapt to wide voltage gain range;...
