What is it about?
Wireless Power Transfer system is new method to transfer electrical energy via air. We have developed a method of charging a Li-ion battery in CC / CV mode through frequency modulation. This method is a way to reduce the additional battery charging circuit, which contributes greatly to the efficiency improvement.
