本设计以双向半桥电路为主拓扑结构，以单片机最小系统板为控制核心，协调各个模块工作以实现题设功能。电路分为主电路拓扑模块、控制模块、PWM控制信号驱动模块、辅助电源模块、电压电流采样模块。(This design takes the two-way half bridge circuit as the main topology, takes the smallest system board of the single chip microcomputer as the control core, and coordinates the work of each module in order to realize the design function. The circuit is divided into main circuit topology module, control module, PWM control signal driving module, auxiliary power module, voltage and current sampling module.)
