Abstract
A power source apparatus for supplying power to a load includes a switch and a controller. The controller detects voltage applied to the switch. The controller further switches a state of the switch from OFF to ON when the detected voltage is equal to or smaller than a predetermined threshold value.
Claims14
A power source apparatus for supplying power to a load, comprising:
- a switch;
- a controller that:
- detects a voltage applied to the switch,
- switches a state of the switch from OFF to ON when the voltage is equal to or smaller than a predetermined threshold value;
- a first DC power source that applies DC voltage between terminals of the switch;
- and
- a compensating circuit that is connected in parallel to the switch and that comprises a second DC power source and a capacitor,
- wherein the controller controls a combined capacitance of parasitic capacitances of the switch and the compensating circuit to be constant by changing a voltage of the second DC power source.
