Abstract
A non-contact power supply device includes an inverter to convert power supplied from a power supply into a predetermined AC power, feeders provided on a track rail to transmit the AC power to a ceiling conveyor, a filter circuit including a reactor and a capacitor, and a controller configured or programmed to perform power control of the AC power that is to be supplied to the feeders. The controller is configured or programmed to obtain a current value output from the inverter while changing a switching frequency of switches of the inverter in a state in which a current having a predetermined value flows through the feeders, and to set and output a reactor value of the reactor and a capacitance value of the capacitor based on the switching frequency at which the current value is minimum.
