摘要
Over the year, magnetic resonance coupled wireless power transfer(WPT), increasingly catching a wide range of eyes, has been introduced into the area of household electrical appliances, both the low frequency of traditional powers and the difficult modulations for frequency and output power according to different load characteristics and requirements are the reasons that this kind product cannot be generalized marketably. In this page, a model of magnetic resonance coupled wireless power transfer system is given with series-series structure. A small power inverter power supply is designed by UCC3895 chip and IR2110 chip, the working frequency up to 500 KHz. The device can realize the function of transmission frequency adjustment and output power adjustment according to load demand. The operating principle of UCC3895 and IR2110 has been discussed in detail, and the page gives the parameter of the device, which can realize the WPT system. Then according to the practical application, a system of wireless charging to Mobile TV is built. The experiment proves the feasibility of the inverter power supply to household electrical appliances.
