  "textContent": "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.",
