A Multi-Function Common Mode Choke Based on Active CM EMI Filters for AC/DC Power Converters [PDF]
IEEE Access, 2019 It is widely believed that hybrid electromagnetic interference (EMI) filter (HEF) is one of the most optimized solutions for EMI elimination. Nevertheless, the desire for a smaller and lighter filtering method has never stopped.

Application of Neural Networks to Estimate Common Mode (CM) Model Impedance Parameters in AC Drives [PDF]
Mathematical and Computational Applications, 2003 Predicting and solving EMI emissions related to Common Mode (CM) ones in inverter (including pulse with modulation (PWM) inverter)-induction motor drive systems requires various frequency-dependent effects to be considered. Thus, the application of filter circuitry to improve the performance per size and prevent dependency on some parameters of the ...

IEEE Open Access Journal of Power and Energy, 2021 Modeling the unintended common- and differential-mode (CM and DM) behavior of multi-converter power electronic-based systems can be a challenge. Chief among the issues is the need for detailed knowledge of the converter hardware to determine model ...
