The Analysis of the Impacts of New Version of IEC 60384-14:2023 on the EMI Problem on Frequency Converters
The problem of EMI in the operation of variable-frequency adjustable speed drive system for servo drive is increasing year by year,and it is urgent to solve the problem of the suppression of the interference generated.IEC 60384-14:2023 Fixed capacitors for use in electronic equipment-Part 14:Sectional specification-Fixed capacitors for electromagnetic interference suppression and connection to the supply mains was formally released in 2023,which puts forward new requirements on the tests and performances of safety capacitors,especially has remarkable impacts on its application in variable-frequency adjustable speed drive system for servo drive,and updates based on the current devel-opment of products and actual testing requirements.This paper compares the differences between IEC 60384-14:2023 and the previous version IEC 60384-14:2013/AMD1:2016,and analyses the old and new standards from several major technical changes,providing reference for relevant manufacturers and testing institutions,also discusses the impact of this standard update on the problem of EMI in variable-frequency adjustable speed drive system for servo drive.
