| Abstract: | The wireless power is a kind of power supply that uses electromagnetic wave to transmit energy, which can economize the use of power cord and plug heads. This paper introduces an electromagnetic induction wireless charger. It＇s combined with magnetic coupling and switching power technology. The system can divide into wireless transmit part and receive part. System et~iciency reaches 67 percent with 1.16W output power when supply voltage is 12V and transmission distance is 3 ram. Test shows that the circuit structure is simple and can work stable. And the 4 light-emitting diodes can be lighted in the range of 6 cm. |
