Title:
A WIRELESS POWER SUPPLY APPARATUS
Document Type and Number:
WIPO Patent Application WO/2004/086588
Kind Code:
A1
Abstract:
This invention relates to the power supply technical field, and provides a wireless power supply apparatus. In the prior art, there needs a power line to a power transformer so that the apparatus is difficult to move, and when it uses a battery, the electric energy will be exhausted so that a consumer can not work. The said wireless power supply apparatus includes a power emitter and a power receiver, and the said power emitter has emitting coils winding a magnetizer and a HF oscillating circuit connected to the emitting coils. The said power receiver is a receiving coil winding the magnetizer. It can convert a DC power or an AC power into a DC voltage,through the HIT oscillating circuit converting a HF voltage which applies to the emitting coils in the power emitter and is emitted by the magnetizer, and then it induces he HF power signal by the magnetizer in the power reveiver, and the receiving coil outputs the signal, thereby it obtains the wireless transfer of the power.
