Abstract
Official abstract text for this publication.
Provided is an over-voltage protection device for a resonant wireless power reception device. The over-voltage protection device includes a resonance signal receiver for receiving a wireless resonance signal transmitted from a wireless power transmission device, an over-voltage protector which is driven by a driver in an over-voltage protection operation to detune a resonance frequency of the reception device, thereby reducing reception power, the driver for driving the over-voltage protector according to a control signal in the over-voltage protection operation, and a controller for outputting the control signal for driving the over-voltage protector to the driver when it is determined that over-voltage occurs.
