一种实用的混合有源电力滤波器的设计和仿真

提出了一种结构简单,实用性比较强的拓扑结构,分析了混合有源滤波器(HAPF)各部分器件参数选取的方法,并介绍开关管关断尖峰电压的抑制措施；实验仿真结果表明,这种混合有源滤波器较好地发挥了无源滤波器(PF)和有源滤波器(APF)的优点,并减小了系统的容量,具有良好的无功电流和谐波电流补偿效果.

Design and Simuulation of One Practical Hybrid Active Power Filter

Hybrid active filter has become a study focus these years. In this paper introduced a simple, practical kind of topology importantly. It analysised the parameter selection methods about each part of HAPF, and describes the suppression measures of voltage spike during switching off.It is shown from the simulation results that the HAPF combining the PF with APF is recommended.The capacity of the system decreases to a great extent.Meanwhile the good performance of displacement power factor and current harmonics compensation is verified by the results.
