Abstract:
1. A power module of a power supply system, said power module being hot-swappable to be connected with a connector of said power supply system or detached from said connector, said power module comprising: a power conversion circuit for outputting a DC voltage; a fan connected with said power conversion circuit; a controlling unit for issuing a control signal to said fan, thereby controlling operation of said fan; a capacitor connected with said fan in parallel; a current-adjusting element connected with said capacitor in series for adjusting the magnitude of current flowing through said capacitor; and a soft start controlling unit connected with said current-adjusting element, wherein when said power module is connected with said connector of said power supply system, said soft start controlling unit controls the magnitude of current flowing through said current-adjusting element to be gradually increased, so that the magnitude of current flowing through said capacitor is gradually increased.
