摘　　要：基于PSIM仿真平台分析了Boost变换器控制电路中电压单环反馈控制方式和以负载电流为内环,输出电压为外环的双环反馈控制方式。从Buck转换器V2的驱动方式出发,设计采用一种以输出电压、输出电流和负载电流为回馈的多环反馈控制方式。仿真结果表明:电压单环反馈控制方式具有较低的反应速率;电压、电流双环反馈控制方式虽然使系统对输入信号的反应速率有所提高,但是对负荷突然变化的反应却没有明显的改善;而电压、电流、负载电流多环控制方式具有动态调节迅速、电压和电流更平稳的特点,是一种很好的控制方法。This design is based on the PSIM simulation platform to analyze the voltage single loop feedback control method and the double loop feedback control method with the load current as the inner loop and the output voltage as the outer loop in the control circuit of the Boost converter.Starting from the driving mode of Buck converter V2,a multi loop feedback control method is designed using output voltage,output current,and load current as feedback.The simulation results show that the voltage single loop feedback control method has a lower reaction rate.Although the voltage and current dual loop feedback control method improves the system's response rate to input signals,there is no significant improvement in its response to sudden changes in load.The multi loop control method of voltage,current,and load current has the characteristics of rapid dynamic adjustment and smoother voltage and current,making it a good control method.
