Abstract

Through the analysis of electromagnetic environment of the HVDC converter valve

it was concluded that electromagnetic compatibility（EMC）test is necessary for the valve-based electronic equipment（VBE）. According to the actual project

the EMC test requirements of VBE were put forward. The test loop was constructed to complete the items of EMC test. A method for suppressing the electrostatic discharge in the test process was proposed

which includes adopting magnetic beads and transient voltage suppressors to improve the luminous drive circuit

restraining interference signals

optimizing PCB layout

modifying grounding mode

and increasing local shield.Test results show that this method can effectively enhance the electrostatic discharge protection capability of the VCM box in the control and protection unit of the converter valve.
