| چکیده | ||
| 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 of PWM inverter, rectifier, DC link, induction motor and long cable. The configuration and design procedure of the proposed filter is presented.The whole system is modeled and simulated by commercially available simulation software. A practical system with EMI measurement system have been suggested to test designed equipment ability in emitting EMI and other adverse effects to comply with electromagnetic compatibility (EMC) standards. The simulation results are verified by experimental results, which show the reduction characteristics of the shaft voltage, bearing current, common mode current, leakage current and EMI. | ||
