Abstract
The present disclosure provides a single-phase three-wire power control system integrating the electricity of a DC power supply device to an AC power source. The single-phase three-wire power control system comprises a single-phase three-wire inverter, a driving unit, a sampling unit and a processing unit. The single-phase three-wire inverter coupled between the DC power supply device and the AC power source converts a DC voltage of the DC power supply device to an output voltage. The driving unit is coupled to the single-phase three-wire inverter. The sampling unit samples the inductor current of an inductor of the single-phase three-wire inverter. The processing unit which is coupled to the driving unit and the sampling unit controls the single-phase three-wire inverter through the driving unit. The processing unit obtains the duty ratio according to the inductance of the inductor, the total variation of the inductor current, the DC voltage and the output voltage.
