摘　　要：针对当前智能高频开关开发需要,提出一种DSP数字化高频开关电源系统。文章首先提出本文的设计目标和系统基本参数要求;其次,结合数字化开关工作原理,提出文章开关电源的控制思想,即采用全桥型DC-DC直流变换器对高频电源开关进行控制;再次,从硬件角度对系统整体架构和主要功能模块进行设计。从软件角度,分别对系统主控制程序进行设计,同时提出一种基于模糊PID的PWM波形控制调节算法。最后对系统的调试,可基本满足设计要求。in view of the current development of intelligent high frequency switch, a DSP digital high frequency switching power supply system is proposed. Firstly put forward the system design goals and basic parameter requirements; secondly, according to the working principle of the digital switch, put forward the switching power supply control of the mind, which uses full bridge DC-DC converter for high frequency switching power supply control. Thirdly, from the angle of the hardware on the system framework and main function module design. From the angle of software, the system main control program is designed, and a PWM waveform control algorithm based on fuzzy PID is proposed. Finally, the debugging of the system can basically meet the design re- quirements.
