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 ...
