Abstract
A solar photovoltaic power conversion system is provided to convert a DC input voltage into an AC output voltage, which mainly includes an input capacitor bank, a first switching circuit, a second switching circuit, a first filtering circuit, a second filtering circuit, and a control circuit. The first switching circuit has a first power switch and a second power switch. The second switching circuit has a third power switch and a fourth power switch. The control circuit produces a first control signal, a second control signal, a third control signal, and a fourth control signal to respectively control the first power switch, the second power switch, the third power switch, and the fourth power switch so as to reduce leakage current of the DC input voltage caused by parasitic capacitance voltage.
