摘要: High density filter design for electromagnetic interference (EMI) noises is essential the variable speed motor drive system in modern transportation applications. As often being one of major causes bulky and heavy designs, mixed-mode (MM) noise phenomenon three-phase discussed this paper. The generation schemes MM on both DC AC sides are analyzed. According to voltage vector modulation, at different switching conditions compared summarized. Based experimental results from a specified prototype system, existence its impact EMI verified. Investigations show that implementation CM balancing X-capacitors can help attenuate effectively.
