Abstract
A resistance switching circuit includes a resistor forming an output resistance of a first power supply. The resistance switching circuit switches between a state in which the resistor forms part of an output resistance and a state in which the resistor does not form part of the output resistance. A control circuit is configured to in a case where a DC voltage with a first polarity is applied to a load from a first power supply, control the resistance switching circuit such that the resistor does not form part of the output resistance, and in a case where a DC voltage with a second polarity is applied to the load from a second power supply, control the resistance switching circuit such that the resistor forms part of the output resistance.
