Types of Hybrid Power Filter and their comparative performance analysis with distorted source voltage using MATLAB

The use of non-linear devices led to the injection of harmonics into the power system. This paper compares the performance of two topologies of Hybrid Power Filters comprising of a Shunt Active and Shunt Passive filters, tuned for 5^th and 7^th harmonics, for compensating harmonics in the power system. The control algorithm proposed in this paper provides an effective harmonic compensation; even the source voltage is having harmonic components. The performance of these topologies of Hybrid Filters was verified through MATLAB/SIMULINK when the source voltage is having a 3^rd harmonic component. The results obtained show that these topologies of Hybrid Filters also allow for reactive power compensation along with harmonic compensation.
