1. A multi-input power system with an inrush current suppression function configured to receive at least two input power sources, the multi-input power system comprising:
at least two filter-rectification circuits configured to respectively receive the at least two input power sources, and convert the at least two input power sources into at least two rectified voltages,
at least two boost power factor correction circuits, each boost power factor correction circuit correspondingly connected to the filter-rectification circuit, and configured to receive the rectified voltage and perform a power factor correction to the rectified voltage to provide a conversion voltage,
a current suppression circuit connected to the at least two filter-rectification circuits and the at least two boost power factor correction circuits, and
a DC-to-DC conversion circuit connected to the at least two boost power factor correction circuits and the current suppression circuit, and the DC-to-DC conversion circuit configured to receive the conversion voltage and convert the conversion voltage into an output voltage.
