Pre-charging circuit, inverter, and power generation system

A power generation system, comprising

• a photovoltaic PV cell;
• an inverter;
• and
• a power grid, wherein the PV cell is connected to the inverter, and the inverter is connected to the power grid;
• the PV cell is configured to convert light energy into a direct current;
• the inverter comprising a capacitor, wherein one end of the pre-charging circuit is connected to a power grid;
• one end of a line formed by the series connection is connected to one terminal of the capacitor, the other end of the line is connected to a first-phase alternating current of the power grid, and the other terminal of the capacitor is connected to a second-phase alternating current of the power grid and a current output by the power grid passes through a closed loop formed by the capacitor to charge the capacitor;
• wherein the inverter is configured to convert the direct current into an alternating current, and perform reactive compensation on the power grid;
• and the alternating current power grid is configured to transfer the alternating current.
