摘要：
This paper presents a simplified Electromagnetic Interference (EMI) filter model to reduce high-frequency noise in the Switched-mode Power supply (SMPS) system. The objective is to design an EMI filter to eliminate the electromagnetic noise that could arise due to the solar power converter (DC-DC and DC-AC) and propagates through the grid. The filter could minimize the EM noise and improve the quality of the power that reaches the grid or to serve as a local load. In this paper, a non-linear source developed using PELCS simulation environment was the origin of the system noise disturbance. Noise injection parallel to the DC-DC converter was injected into the current source. The presented methodology provides sufficient data for EMI modelling and mitigation purposes. The model could also be adapted to further study the conducted and radiated emissions carried out in the system. The model of the noise source permitted various high-frequency injection at given times and assessed the efficiency of the EMI filter in EMI mitigation.
