NON-CONTACT POWER TRANSMISSION SYSTEM

A non-contact power transmission system includes a power reception unit, a received power conversion unit, a current sensor, and a control device. The power reception unit includes a secondary side coil for receiving AC power transmitted in a non-contact manner from a primary side coil of a power transmission device. The received power conversion unit converts AC power received by the power reception unit into DC power. The current sensor detects a current flowing between the power reception unit and the received power conversion unit. The control device executes a synchronous rectification operation by synchronously driving a plurality of switching elements of the received power conversion unit in accordance with a phase of the current when a detection value of a current output from the current sensor is equal to or larger than a predetermined threshold.
