Abstract: Harmonics elimination in a distribution system has become a major point of focus in the presesnt age scenario. This paper presents harmonic elimination by employing hysteresis current controller(HCC) based Hybrid active power filter(HAPF) in the distribution system. Hybrid Active Power Filter(HAPF) shows great promise in reducing harmonics and improving the power quality in comparision to Shunt Active Power Filter(SAPF). Hybrid active power filter with two level hysteresis current controller is introduced along with indirect current control technique. A three phase insulated gate bipolar transistor (IGBT) with a dc-bus capacitor and passive power filter together is used as Hybrid Active Power Filter. Initially the reference current is extracted from the nonlinear load current by applying the indirect current control method and then the reference current is fed to the proposed controller for generation of switching signals. The nonlinear load consists of one three-phase and one single-phase diode rectifier feeding R-L load, so that the effectiveness of the two-level HCC scheme to compensate harmonics for unbalanced nonlinear load can be tested. For the performance analysis, various simulation results of HAPF with HCC are presented. The simulation results show that the indirect current control method is not only easy to be calculated but also very effective in elimination of harmonics in a distribution system.
