PROBLEM TO BE SOLVED: To effectively reduce the torque required to rotate the rotor of a generator, when the generated power of an AC generator involving a rotor rotated by a manual rotating driving mechanism is converted into direct current and supplied to a load through a DC voltage converter. SOLUTION: This power supply system is provided with a three-phase AC generator 11 having a stator and a rotor, a manual rotational drive part 12 and an accelerating part 13, for making the three-phase AC generator 11 conduct generating operation by rotatingly-driving the rotor of the three-phase AC generator 11, a three-phase commutation smoothing part 45 for obtaining a DC voltage based on the output voltage of the three-phase AC generator 11, a DC voltage converter 60 which forms a converted DC voltage having a value smaller than the DC voltage obtained from the three-phase commutation smoothing part 45 and supplies the converted DC voltage and DC current accompanied by it to a secondary cell 48 or a power storage capacitor 49, and an operation control part 50 for keeping the DC voltage converter 60 in an inoperative condition, when the output voltage of the three-phase AC generator 11 is a prescribed value or lower. |
