具有多路阶梯波电压的串并联型包络跟踪电源

The series–parallel-form switch-linear hybrid envelope tracking (ET) power supply features high efficiency and high bandwidth. In this structure, two multilevel converters are used to fit the load voltage, and a buck converter is used to track the load current. As the bandwidth and the peak-to-average power ratio of the radio frequency signal continue increasing, the buck converter needs to operat...
