ABSTRACT
In this paper, we enhance the power quality, Harmonic reduction, Reactive power compensation. Power quality problems have become the most important concern now days. Custom Power Devices (CPD) provides a solution for these power quality problems. Shunt active power filter is the preeminent solution against nonlinear loads, power quality problems, and current harmonics. The HPF includes a series passive filter and a thyristor-controlled-reactorbased variable-impedance SPF i.e shunt passive filter. A novel circuit topology for the three-phase APF - active power filter is A novel circuit topology is proposed to suppress harmonic currents. This three-phase APF is made up of a twoarm bridge power converter, a filter inductor set, a reactive power compensating capacitor set and a capacitor/resistor filtering set. The proposed topology enhances the harmonic compensation capability and provides complete reactive power compensation compared with conventional APF topologies
