摘要
如何结合整个控制系统,设计满足要求的有源功率因数校正电路已成为实际应用中必须面对的问题。主电路运用简单高效的Boost型功率因数校正电路,并在电路控制系统采用电流、电压两个闭环,对电流环采用PI控制。用Simulink软件建立了仿真电路,分析PI参数在电力电子开关控制中对输出电压的影响,证明了双闭环PI控制方法解决谐波污染的有效性。
How to combine the entire control system to design an active power correction circuit meeting requirements became practical problems that must be faced. Simple and efficient Boost-type power factor correction was applied as the main circuit. Also two closed-loops, current and voltage loop, were adopted in the system of circuit control and the PI control was used in the current loop. A simulation circuit was built using Simulink. The affect of PI parameters on the output voltage was analyzed in power electronic switch control. The validity of two closed-loops PI control method for solving harmonic pollution is proved.
