Abstract:
The present invention relates to a technique for expanding an input voltage range of a power conversion circuit for photovoltaic power generation, and improving the efficiency of the power conversion circuit. The power conversion circuit for photovoltaic power generation with high efficiency over a wide input voltage range may include: a full-bridge converter unit including a full-bridge converter constituted by first to fourth switches, and configured to operate in a resonant boost mode or phase-shift full-bridge series-resonant converter mode, and convert an input DC voltage into a DC voltage having a level equal to or lower than the input DC voltage; an active voltage-doubler rectifier circuit including a half-bridge converter constituted by fifth and sixth switches, a resonance inductor and a resonance capacitor, and configured to boost an input voltage to a target-level DC voltage, and output the DC voltage to a load; and a transformer configured to connect the full-bridge converter and the active voltage-doubler rectifier to each other in their insulation.

Claim (Index 10):
The power conversion circuit of  claim 5 , wherein when the full-bridge converter unit operates in the fifth resonant boost mode,\n the second and third switches and the fifth switch are turned on, and the first and fourth switches and the sixth switch are turned off, so that electrical energy stored in the resonance inductor rapidly increases, and power of a primary coil of the transformer is transferred to a secondary coil.
