To provide a power supply system capable of achieving compaction and weight-saving.SOLUTION: A power supply system 100 for supplying power of a power supply 1 to multiple loads 21-23 includes a fuse 2 having one end connected electrically with the power supply 1, multiple semiconductor switches 11a, 12a, 13a electrically connected between the other end of the fuse 2 and the multiple loads 21-23, respectively, a control arrangement 40 having a receiving part 41 for receiving an ON/OFF instruction signal of the semiconductor switches, and controlling ON/OFF of the multiple semiconductor switches 11a, 12a, 13a, and a current sensor 20 for detecting a current flowing from the power supply 1 to the multiple semiconductor switches 11a, 12a, 13a via the fuse 2. The control arrangement 40 performs PWM control of the multiple semiconductor switches 11a, 12a, 13a, on the basis of at least one of the reception results of the receiving part 41 and the detection results of the current sensor 20.SELECTED DRAWING: Figure 1 【課題】小型化や軽量化を図ることができる電力供給システムを提供する。【解決手段】電源１の電力を複数の負荷２１〜２３に供給する電力供給システム１００は、一端が電源１と電気的に接続するヒューズ２と、ヒューズ２の他端と複数の負荷２１〜２３の間にそれぞれ電気的に接続された複数の半導体スイッチ１１ａ、１２ａ、１３ａと、半導体スイッチのオン及びオフの指示信号を受ける受信部４１を有し、複数の半導体スイッチ１１ａ、１２ａ、１３ａのオン及びオフを制御する制御装置４０と、電源１からヒューズ２を介して複数の半導体スイッチ１１ａ、１２ａ、１３ａへ流れる電流を検出する電流センサ２０と、を備え、制御装置４０は、受信部４１の受信結果及び電流センサ２０の検出結果の少なくとも一方に基づいて、複数の半導体スイッチ１１ａ、１２ａ、１３ａをＰＷＭ制御する。【選択図】図１
