摘要：This p.p.r p.esents the design of a controller for the measurement and reduction of conducted Electro Magnetic Interference (EMI) caused in the p.wer electronic circuits. The conducted EMI is also sep.rating the Common Mode (CM) and Differential Mode (DM) simultaneously using Line Imp.dance Stabilization Network (LISN). EMI is mitigated by the fuzzy controller. By comp.ring common mode voltage with the standard reference value, the generated error can be minimized by using fuzzy controller. Fuzzy controller is varying the p.M signal of the p.wer electronic switching devices for reducing the electromagnetic interference. In this p.p.r, comp.rison of p. and fuzzy controller of the op.n loop.and closed loop.models are imp.emented using MATLAB&amp.reg SIMULINK for measurement and reduction of the EMI level;and also simulation results of the p. controller and fuzzy controller analysis are p.esented in this p.p.r. The fuzzy controller is p.ovided to achieve the EMI level of the inverter within the standard limit.
