Design and Implementation of a Hybrid Series Active Power Filter

This paper presents a single-phase series active power filter, which adopts the structure of shunt combination of passive filter and active power filters, thus is suitable for compensating voltage type harmonic producing load and the voltage distortion by the load terminal in the power system. The proposed scheme detected both source current and load voltage to calculate the reference signal of the compensation voltage, the proposed method provides voltage harmonic elimination for power system. The digital signal processor (TMS320F240) controller is used to implement the control method. Finally, the feasibility of the proposed hybrid control is verified from the experimental results
