Patent ID: 8067853

Claim:
A power supply system that supplies electric power to electric loads including actuators, the electric loads being mounted in a movable body, the power supply system comprising: a generator that generates electric power of a first voltage; a transformer circuit that boosts the electric power of the first voltage to a second voltage; and a battery that is connected, via the transformer circuit, to the generator and that stores electric power of the second voltage obtained by the boosting by the transformer circuit, wherein at least one of the actuators is connected on the generator side of the transformer circuit, so as to be supplied with the electric power of the first voltage, the electric loads include a control device that controls a moving function of the movable body, the control device is connected on the battery side of the transformer circuit, the actuators include a controlled actuator whose drive is controlled by the control device, the controlled actuator is connected on the generator side of the transformer circuit, and the battery side and the generator side are connected to each other only via the transformer circuit that boosts the electric power of the first voltage to the second voltage.
