摘　　要：主要讨论功率电路的设计方法。功率电路的设计主要和系统的稳态工作特性有关。因此首先对串联型有源电力滤波器进行了稳态分析 ,建立了系统的等效电路。然后 ,根据等效电路提出了一套基于稳态分析的功率电路设计方法。利用该方法推导出了功率电路设计所要求的各个部分与电网电压畸变率、额定负载、负载功率因数及系统是否进行无功补偿的关系 ,得到了明确的解析表达式。所提方法和推导的结果均通过了实验验证。The design methods of the power circuits are mainly discussed.It is mainly relational to the steady state operating characteristics of SAPF.The steady state analysis of SAPF is presented and its equivalent circuit is given,based on which a set of design method for power circuit of SAPF is brought out.Using the methods,the relations between the power circuit and the distortion ratio of utility voltage,the rating load,the power factor and the VAR compensation conditions are then analyzed,and the analytical expressions are derived.The introduced methods and results are experimentally verified.
