High voltage power supply (HVPS)is one of the most important component in ECRH. The safety and reliability of high voltage power supply affect directly the operation of the ECRH system. The fundamental theory of electromagnetic interference is analyzed in this paper. Deal with the space electromagnetic interference and other interference source, a few measures of interference suppression are proposed in the aspects on the defence of system, signal transmission and manufacture technology etc. Simulation and experiment show that the measures of interference suppression advanced in this paper have better characteristics.
