摘要
首先介绍线性系统的传输函数以及用波德图表示它的频率特性的方法、零点、极点的概念等,在此基础上讨论有源功率因数校正电路中电压放大器和电流放大器补偿网络的作用,给出有关补偿元件的计算方法。
The transfer function of a linear system is are introduced at first,and then the method of describing the frequency characteristics by bode plot,zero points and pole points is presented.The role of compensation networks of voltage and current amplifier used in active power factor correction regulators is discussed and the estimation methods of compensation networks are given.
