Abstract :
One-cycle control active power filter (OCC-APF) with vector operation is a promising method to cancel harmonics and correct power factor. It features simple circuit, high performance, and excellent stability. This paper studies the performances of both the steady-state and dynamics. The stability condition for three-phase OCC-APF is first derived. Some typical large signal perturbations and the tracking ability for the fast transient are investigated, which provides guidelines for the design of the control circuit and the main circuit. All analysis and results were verified by simulation and experiments based on a three-phase 5 kW pre-industrial OCC-APF prototype.
