摘要： A circuit for converting a direct current voltage into an alternating current voltage includes a buck converter, a resonant DC voltage/DC voltage converter, a DC voltage/AC voltage inverter, and a DC link capacitor. The buck converter generates a DC current according to an input voltage generated by a voltage source operating at an optimal operation point. The resonant DC voltage/DC voltage converter converts the input voltage to a DC voltage according to a switch clock and a resonant frequency determined by a resonant capacitor and a resonant inductance of the resonant DC voltage/DC voltage converter. The DC voltage/AC voltage inverter converts the DC voltage and outputs an AC voltage to an AC power supply network. The DC link capacitor adjusts power outputted by the DC voltage/AC voltage converter to regulate the DC voltage.
