Abstract
A multi-input power system receives at least two input power sources, and includes at least two filter and rectification circuits, at least two boost PFC circuits, a DC-to-DC conversion circuit, and a control circuit. The filter and rectification circuits correspondingly receive the input power sources, and convert the input power sources into rectified voltages. The boost PFC circuits correspondingly receive the rectified voltages and perform a power factor correction on the rectified voltages to provide a conversion voltage. The DC-to-DC conversion circuit converts the conversion voltage into an output voltage. The control circuit receives power information corresponding to the input power sources and determines power supply status of the input power sources according to the power information to generate control signals. The control signals are provided to correspondingly control the boost PFC circuits to control the magnitude of the conversion voltage.
