Design of a Shunt Active Power Filter for Direct Matrix Converter Application

Direct matrix converters (DMC) are a family of cycloconverters that allows the possibility of any phase (fixed or variable) to be converted to another without the traditional dc link capacitor. The absence of energy storage components makes the DMC suitable for several applications where size and weight are of much concern. Notwithstanding, filter selection for the high frequency ripple mitigation of the input to the DMC applications must be appropriately designed as it would affect its dynamic performance. This paper presents a shunt active power filter (SAPF) with a Neuro-Pi control strategy for the DMC application. Experimental results from MATLAB/SIMULINK are presented to validate the proposed design.
