Simulation and Verification of Common Mode Voltage in EDS
Common mode(CM)voltage is a key index to be suppressed in the electric drive system(EDS),which not only affects the test results of electromagnetic disturbance,but also has great harm to bearing corrosion and other reliability aspects.Research on the generation mechanism of common mode voltage and verification are the preconditions to suppress the common mode voltage.In this paper,the generation mechanism of common mode voltage is analyzed,and the common mode voltage models under different working conditions are studied and verified by experiments.
