摘要
有源电力滤波器(Active Power Filer)的数学模型对于控制器设计及交直流能量传递分析具有重要意义。针对目前广泛使用的并联型APF主拓扑结构建立数学模型,并在此基础上使用一种不定频滞环SVPWM电流控制策略。详细分析并建立了三相三线制APF数学模型,给出了控制器设计方法。经仿真与实验验证表明,建立的并联型有源电力滤波器的数学模型是正确的,其控制策略具有一定的参考价值。
The mathematical model of active power filter （APF） has important implications for the design of controller and the analysis of AC/DC energy transfer. On the basis of the mathematical model established for widely used parallel APF main circuit topology, a circuit control strategy of variable frequency hysteresis SVPWA is used. Three-phase three-wire APF model is analyzed and established in detail, and the design method of controller is given. The simulation verification confirms that the mathematical model of parallel APF established is correct, and the control strategy could be a very good reference.
