DC Side Active Power Filters for Aircraft Electric Power Systems 929496

In this paper a new dc-side active filtering system is proposed for aircraft electric power systems. The proposed active filter provides a continuous adjustable reactive power (both in phase and frequency) in the dc-link to meet the changing requirements which arise due to unbalanced and nonlinear loads at the 400(Hz) output. Furthermore, the active filter eliminate the additional capacitive kVA required in the dc-link caused by unbalanced and nonlinear loads. Results from a laboratory prototype active filter are also discussed.
