摘要
文中采用状态空间平均法对级联Buck-Boost AC-DC变换器进行了小信号建模分析,提出了一种基于瞬时功率守恒的新的平均电流控制(ACC)技术。通过这种新的控制技术能够使得输入电流波形接近正弦波且与输入电压同相位,总的谐波扰动小于3%。最后通过PSIM仿真实验,验证了这种新的控制方法的可行性和优越性。
By Using the method of state-space averaging method,and applying small-signal modeling analysis on cascaded Buck-Boost AC-DC converter,this paper presents a new average current control(ACC)technique based on instantaneous power balance(IPB)law.This new controlling technology makes the input current waveform closer to sine waves and have a same phase with input voltage,and makes the total harmonic distortion(THD)lower than 3%.The PSIM simulation verity this method practically and superiority.
