Reduction and Elimination of Harmonics using Power Active Harmonic Filter
International Journal of Recent Technology and Engineering, 2019 The Three Phase 4 wire Harmonic Filter is used to mitigate harmonics which is caused by expanding utilization of present day control electronic system and mechanical assembly drives, uninterruptible power supplies, SMPS and so on. These are responsible of producing nonlinear current and accordingly stack in the system with Harmonics. The capacitance of
