According to the working principle of series active power filter, the principle, system structure and characteristics of the control method for detecting power supply current and load voltage are discussed. Based on this, the compound control method is analyzed, and the comparison of the three control methods is made. The experimental results show that when the voltage harmonic source is used to compensate, the series active power filter adopts the compound control method with high stability and good harmonic compensation effect.
