Abstract

The orthogonal transformation technique which was instigated by Akagi et al in 1984 for the investigation of the instantaneous power in a three phase power system is extended in this paper in order to derive novel compensating current expressions for a single phase, shunt active power filter. This filter is used for a single phase power supply feeding a non-linear load in order to compensate for the instantaneous reactive power or the harmonic current distortion or for compensating of both. The configuration of the active power filter utilised in this investigation is included. In addition, the filter compensating current control technique and methods implemented for the evaluation of the filter ratings and size are included. An expression for the distortion power equation for a single phase power supply feeding a non-linear load is derived in the Appendix. This expression is extremely useful as an aid to design active power filters which compensate for both of the reactive power and the current higher harmonics. Experimental results demonstrated the effectiveness of the novel expressions for the active power filter compensating currents derived in this paper.
