The main objectives of this paper are to improve power factor and reduce harmonic distortion in the supply voltage and current, thereby improving power and/or voltage quality of the system. The harmonic distortion due to the development of power electronic- based equipment is discussed in this paper. To resolve the energy flow issue due to non-linear loads, we present a new closed loop control system with a simple linear integrated circuit which is proposed for the shunt triggering compensator (STC). The STC is investigated through Matlab simulation for under unbalanced supply and load conditions and simulated results are compared with hardware results.
