摘　　要：交流电感是并联型有源电力滤波器(APF)的关键参数之一,并与所补偿的电流谐波特征有关。在给出满足电流跟踪能力的APF电压约束方程的基础上,推导出了APF交流电感的取值范围。根据所选交流电感应尽量小的原则,进一步给出了APF交流电感的额定值计算公式。同时讨论了直流电压的选择方法,并给出了直流电压额定值的计算公式。所给出的公式具有能够满足特定负载类型所有工况下的补偿要求、易于考虑所补偿的电流谐波特征以及便于计算和理论分析的优点。通过与其他文献结果比较,说明所提思路及其结果是正确有效的。Abstract： AC inductance is a key parameter of shunt APF（Active Power Fiher）,which is related to the harmonic characteristics of compensation current. The AC inductance range of APF is derived based on its voltage constraint equation with satisfied current tracking capability and the formulae for calculating the rated AC inductance based on the principle of possible smaller AC inductance are given. The methods of DC voltage selection are discussed and the formulae for calculating the rated DC voltage are given. The given formulae are convenient for calculation and theoretical analysis,which consider the harmonic characteristics of compensation current expediently and satisfy the compensation requirements of specific load type in all conditions. The comparison with the results by other relative theses shows the presented concepts and conclusions are correct and effective.
