Construction and Test Research of On-load Radiation Emission Test Platform for Traction Converter
According to the requirement of on-load radiation emission test of rail vehicle traction converters,the structure and disturbance source of traction converter are analyzed and summarized,then the structure of the on-load radiation emission test platform based on the semi-anechoic chamber is described.Through high voltage power supply system and the back-to-back mode of the motor,the requirements of on-load radiation emission test are realized,and the test method of traction converter is further studied.Finally,radiation emission tests were carried out on the traction converter of a certain type of EMU under different working conditions,which verifies the feasibility of the test platform.Meanwhile,through comparative analysis of the test data,the radiation emission of the traction converter under different frequency bands and working conditions and the suppression effect of adding magnetic rings at different positions are summarized.This paper provides data reference for the research of electromagnetic compatibility of traction converters and the formulation of standard limits.
