Abstract


In this paper, the UHV project , focusing on the role of the radiated electromagnetic field the converter valve control circuit board and UHV secondary open into the open board interference problems , first from the calculation theory of finite integration method and finite element method analysis simulation package PCB anti-jamming analysis algorithms, general measures to trace layout ; based CST and HFSS packages , simulation analysis , analysis of different directions , different polarization direction of the plane wave irradiation to the PCB as well as the impact of impact on the PCB , the current analysis of the long wire loop formed by intensive components at the size of the induced voltage , the surface current flows , and the electromagnetic field convergence value ; subsequently combined with the physical model , and design of transmit antennas based on the plane wave irradiation test , combining simulation and test results on the PCB kind of appropriate corrective measures .
