Description
Summary:This paper describes a new technique for shunt connected harmonic compensation of a single-phase system feeding non-linear load. An active current wave-shaping boost rectifier technique is proposed to mitigate the distortion current by injecting equal but opposite current to shape the pulsating nature of the supply current to a sinusoidal form and in-time phase with the supply voltage. This is implemented as a shunt active power filter. Only one power switch is employed to minimize cost, reduce switching stress and losses. A peripheral interface controller (PIC) was used to synthesize the required injected current. The behaviour and operation of the proposed filter structure was examined with computer simulation and verified experimentally.
