Abstract
An output device outputs a DC voltage applied between a first terminal and a second terminal via the drain and the source of a semiconductor switch. The output device includes a conversion circuit configured to convert the DC voltage into a voltage of a predetermined polarity, irrespective of the polarity of the DC voltage. A booster circuit boosts the voltage that was converted by the conversion circuit and applies the boosted voltage to the gate of the semiconductor switch. The semiconductor switch is on if the voltage of the control terminal with respect to the potential of the first terminal is at least a predetermined voltage.
