Abstract

For the radiated EMI (Electromagnetic Interference) noise generated by the inverter power supply, this paper studies the EMI noise suppression based on the electromagnetic shielding of the cabinet. By modeling the inverter power cabinet in the CST simulation environment, the electromagnetic shielding effect of the cabinet under different cabinet models is analyzed, and the simulation results are analyzed to optimize the shielding effectiveness of the cabinet. Finally, it is applied to the specific case and adopted rectification. After the suppression measures, the tested equipment can successfully pass the test and verify the effectiveness of the method. This paper provides a reference and basis for the research of radiated electromagnetic interference noise of inverter power supply and the later rectification of technicians.
