RECEIVED POWER CONVERSION DEVICE FOR RESONANT WIRELESS CHARGING SYSTEM
First Claim
1. A received power conversion device for a resonant wireless charging system, the received power conversion device comprising:
- a wireless power receiver for receiving wireless power transmitted from a wireless power transmission device;
a rectifier for rectifying power in an Alternating Current (AC) form received in the wireless power receiver into a Direct Current (DC);
a free-wheeling switching unit for performing a switching operation according to a switching control signal and forming a path for free-wheeling the power in the AC form received in the wireless power receiver;
a feedback circuit fed back with an output signal of a corresponding power conversion device and detecting a level of the output signal; and
a controller for controlling a switching operation of the free-wheeling switching unit according to the output level detected by the feedback circuit.
