Claim:
1. A power conversion apparatus whose output terminal is connected to an electric load, and which converts an input voltage and supplies an output voltage to the electric load, the power conversion apparatus comprising: a semiconductor switch which switches between an open state and a closed state to regulate a voltage control current for controlling the output voltage; a first voltage detection section which detects a remote voltage which is applied to the electric load as the output voltage; a second voltage detection section which detects a local voltage which is applied to the output terminal as the output voltage; a target current calculation section which calculates a target current, which is a target value of the voltage control current, based on a voltage deviation between i) a target voltage, which is a target value of the output voltage, and ii) either the remote voltage or the local voltage; and a switch control section which controls the semiconductor switch so that the voltage control current becomes the target current, to regulate the output voltage to the target voltage, wherein the target current calculation section calculates the target current by using whichever one of the remote voltage and the local voltage corresponds to a smaller target current.
