PROBLEM TO BE SOLVED: To downsize a power supply system which supplies a load with power generated with a generator.SOLUTION: The power supply system 1 includes a rectifier 11, which converts AC power generated with the generator 2 into DC power, a switch element Q, which breaks the generator 2 off the load 3 or connects them with each other, and a control unit 12, which controls the switch element Q. The control unit 12 sets a duty ratio of the switch element Q, according to a voltage, which is rectified with the rectifier 11 from an AC voltage output from the generator 2, and a duty ratio of the switch element Q, and supplies control signals to a gate of the switch element Q at the set duty ratio. |
