Many practical photovoltaic power generation systems with higher output voltage levels rely on photovoltaic DC boost converters with high frequency and high efficiency, which performance directly affect the conversion efficiency of photovoltaic power generation systems. This paper investigates a high-frequency and high-efficiency photovoltaic DC boost converter, which adopts the Boost full-bridge isolation circuit topology with active clamps. The conductance increment method is used as the maximum power point tracking algorithm. The small signal models of its power circuit and control circuit are established to obtain the system model and analyze its stability. The simulation results indicate that the ripple coefficient of output current is less than 3%, and the ripple coefficient of output voltage is less than 5%, which meets the stability requirements.
