Simulation and Experimental Investigations on a Shunt Active Power Filter for Harmonics and Reactive Power Compensation

摘要

This paper presents a 3-phase shunt active power filter, which is capable to compensate the harmonics and reactive power required by non-linear loads. A shunt active power filter system has been simulated and its performance is investigated under steady state and transient conditions. A laboratory model has been developed to verify the simulation results. The control scheme has been realized on a dedicated micro-controller (INTEL-8031) based system. The compensation process is simple, which operates without sensing the harmonics or reactive volt-ampere requirement of the load. PWM pattern generation is based on carrierless hysteresis based current control to obtain the switching signals of the PWM converter.
