Because a bulk smoothing capacitor is usually installed on the DC side of many AC to DC converters, the characteristics of harmonic loads will be influenced by this capacitor. Nowadays, shunt active power filters can't reduce harmonics effectively for this voltage type harmonic-producing load. Therefore, a series active power filter is designed to meet the requirements of voltage-sourced harmonic loads. Both source current and load voltage are detected in order to reach the compensation voltage for the SAPF.

由於许多交直流电源转换器均在直流端并联一直流电容以作为稳压之用，此大电容将造成负载谐波特性的改变；此类谐波源负载，如果使用现今常见的并联型主动式电力滤波器并不能很有效解决此类谐波问题；因此本文将采用串联型主动式电力滤波器，并配合同时量测电源电流及负载电压的混合式控制模式，即可有效解决此类谐波问题。
