Abstract
一种充电器和控制方法，包括：变压器(240)；至少一个初级侧开关管(231)，用于对输入该变压器的电压进行斩波调制；第一控制单元(211)；第二控制单元(212)，用于基于该充电器输出端输出的电压和/或电流信息生成反馈信息；第一微波单元(221)，分别与该第一控制单元(211)和该第二控制单元(212)连接，用于将该反馈信息传输给该第一控制单元(211)；该第一控制单元(211)用于根据该反馈信息，输出第一控制信号，以控制该至少一个初级侧开关管(231)的导通或关断。该充电器驱动速度快，死区时间可精确控制；同时也可以隔离第一开关管产生的寄生电容的传输。由于采用第一微波单元(221)进行隔离通信，可以实现快速双向通信，从而可以提高通信的快速性、灵活性和安全性。
