Power Receiver

A power receiver includes a pickup coil, a rectifier, a chopper, a controller that controls an on-duty cycle of a switching element in the chopper, a voltage detector that detects an output voltage, and a current detector that detects an output current. The controller controls the on-duty cycle of the switching element based on the output voltage and the output current to cause power less than or equal to a preset power to be supplied to an electric load.
