Abstract

A power transmitter is a device for wirelessly supplying power to a power receiver, including: a power converter configured to convert power supplied from a power source into direct current (DC) power; a DC/alternating current (AC) converter configured to convert the DC power into AC power; a capacitor configured to be provided at an input of the DC/AC converter; and a controller configured to perform a discharge control of the capacitor after the power converter stops, wherein the controller performs the discharge control by changing at least one of a driving frequency and a phase shift amount of the DC/AC converter so that power supplied to the DC/AC converter by the capacitor is equal to or lower than withstand power of the DC/AC converter.
