摘　　要：为了解决手机传统有线充电方式接线繁杂、插口易损、二次利用率低等问题,设计了基于STM32的无线传能手机充电器[1]。根据两线圈磁耦合谐振式无线电能传输原理,利用逆变与整流电路实现电能转换,发射与接收部分均采用串联型谐振的SS型拓扑完成能量传输,这一结构可使传输效率大大提高。经过测试,该无线传能手机充电器输出功率为2.5~5.0 W,并具有过压过流保护功能。In order to solve the problem of complex wiring,vulnerable of socket and low utilization rate of the traditional mobile phone,the wireless mobile charger based on STM32 was designed.According to the principle of two coil magnetically coupled resonant radio transmission,inverting and rectifying circuit was used to realize electric energy conversion.The series resonant type SS topology which could greatly improve the transfer efficiency was adopted by transmitting and receiving module.After testing,the output power of the wireless mobile phone charger was 2.5~5.0 Wand the charger has the function of over voltage and overcurrent protection.
