This report is about the development of an active power filter used for filtering nonlinear current. The source of the nonlinear current is a fan system consisting of two parallel connected BLDC motors. A bi-directional power converter is designed analytically which is verified by simulations and a practical prototype. The outcome of the report is a simulation that is used to verify the performance of the active power filter and a cost and size analysis to compare a conventional passive filter used today with the active filter designed for this application. The final result was an active power filter that was 6:8 times more expensive in material cost and the same size as the conventional passive filter.
