摘要
共模(CM)电压是电驱系统(EDS)需要抑制的关键指标,不仅会影响电磁骚扰测试结果,其累计效应对轴承腐蚀等也具有非常大的危害,研究共模电压的产生机制并进行验证是抑制共模电压的前置条件.鉴于此,分析了共模电压的产生机制,研究不同工况下的共模电压模型并进行实验验证.
Abstract
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.
