Abstract

Instead of analog Electromagnetic Interference (EMI) filters, digital filters have been the alternate EMI mitigation solution in power converters to overcome the passive and analog active filters ‘limitations such as size, cost, size and high power consumption. In this paper, Common Mode (CM) EMI digital filter based on the use of fuzzy logic technique, is proposed. The filter is modeled and integrated in a field programmable gate Array (FPGA) device. Matlab/Simulink environment is used for the co-simulation PSpice/Simulink and the block sets of Xilinx System Generator (XSG) has been used for a rapid prototyping. The figure-of-merit of the proposed EMI filter is presented. The simulation results using MATLAB/Simulink have been discussed.
