Abstract:
A power system and a starting method thereof includes a power output circuit, a loop circuit, a soft start circuit, and a constant-current source that supplies power to the soft start circuit. The loop circuit includes a loop circuit capacitor. The power system further includes a precharge circuit that charges the loop circuit capacitor, and the precharge circuit charges the loop circuit capacitor when the soft start circuit charges the power output circuit.
