This paper presents novel active filter for mitigation electromagnetic interference (EMI) and other adverse effects of pulse width modulation (PWM) inverter-fed AC motor system. An active filter proposed and devised for this system is characterized by sophisticated connection of two small separate filters, capable of mitigating all the adverse effects. This paper provides high frequency models ...

What is the problem? Electromagnetic Interference is the Electromagnetic emission from a device or a system that interferes with the normal operation of another device or a system (external source). It is also referred to as Radio Frequency Interference (RFI). EMI is caused by electromagnetic induction or electromagnetic radiation emitted from an external source. Conducted EMI and Radiated EMI ...

This paper studies the electromagnetic interference problems arising in corridors shared by transmission lines, pipelines, and railways, etc. A new circuit model method for analyzing interference problems is introduced. This method can be used to compute the combined inductive, capacitive, and conductive interference level efficiently and accurately. Practical examples are examined and results ...
