CPC H02J 50/12 (2016.02) [H02J 2310/40 (2020.01)] | 4 Claims |
1. A power receiver installable in a movable body to receive power supply contactlessly through a feed line installed along a movement path for the movable body, the power receiver comprising:
a pickup coil configured to generate an induced electromotive force using an alternating current flowing through the feed line;
a rectifier connected to the pickup coil;
a chopper configured to regulate a voltage rectified by the rectifier and supply the voltage to an electric load in the movable body;
a controller configured to control an on-duty cycle of a switching element included in the chopper;
a voltage detector configured to detect an output voltage of the chopper; and
a current detector configured to detect an output current of the chopper,
wherein the controller controls the on-duty cycle of the switching element based on the output voltage detected by the voltage detector and the output current detected by the current detector to cause power less than or equal to a preset power to be supplied to the electric load.
