The Research Of EMI In Power System Secondary Equipment PCB

The research base on the project of high voltage,mainly studies the electromagnetic radiations of HVDC convert valve PCB and high voltage secondary equipment board's EMI. First,this essay uses Finite Integration Theory and Finite Element Analysis Method analysis the Anti-interference calculations of the simulate software,and gives some normally methods of layout.Secondly,base on CST and HFSS,this essay simulates different direction,different polarization direction of incident wave propagation,and analysis the induced voltage,electric field,magnetic field intensity and surface current at the loop.Finally,this essay use the real PCB,design a plane-wave radiation test,according the test and simulation this essay puts a specific rehabilitation scheme.
