T. Paulraj, M. Arun Prakash.
Keywords: non-linear load; current harmonics; instantaneous reactive power theory; sinusoidal current.
ABSTRACT: Prominent harmonics in IT offices are essentially due to the presence of SMPS in computers large numbers. In a three-phase, four-wire system, current harmonics leads to flow zero sequence current in neutral conductor, increased losses in motors, false tripping of circuit breakers. In this paper, VSI is designed as a compensator based instantaneous reactive power theory. And is used to mitigate the current harmonic caused by 6 pulse diode rectifier is mitigated. Simulation is done with MATlab software and results are verified.
