Design of DSP Intelligent Control System Based on Soft Switching Power Supply

介绍了一种基于DSP控制车载软开关电源系统。该电源系统引入软开关技术减小功率器件开关损耗,设计了一种基于全桥移相DC-DC软开关变换器的数字化逆变车载电源,控制系统以DSP为控制核心采用电压模糊PI自校正控制电压外环与带电流峰值限制控制电流内环的双闭环控制模式。

This paper introduces a kind of DSP control system based on soft switch power supply vehicle.The power system into the soft switching technology to reduce the switching loss of power device,and presents the design of a digital inverter power phase shifted full bridge soft switching DC-DC converter based on the control system,using DSP as the control core,uses the voltage fuzzy PI self-tuning control voltage outer loop and charged current peak limit of double closed loop control mode control current loop.
