A new technique for three-phase active power filter

A three-phase harmonic current cancellation scheme based on optimal pulse width modulation (PWM) current injection using a novel time sharing technique (TST) is presented. A novel three-phase current source inverter topology is described, which is simpler and requires components of lower power rating than conventional circuits. The performance of the active filter is investigated by simulation and experiment. Experimental results indicate that the system performs as expected and give good agreement with theory and simulation studies. The active power filter is especially suited to cancel harmonics generated by rectifier and thyristor loads.<<ETX>>
