Some Approaches to Reduce Total Harmonic Distortion & Common Mode Voltage of Inverter Fed Induction Motor

摘要

A novel passive filter is proposed in this paper, with an objective of eliminating the common-mode and differential-mode voltage generated . For determining the parameters of filter, the filter transfer function is utilized to achieve a desirable filtering performance. The detailed design procedure of the filter parameters is given. The validity and effectiveness of proposed filter are supported by the simulation and experimental results carried out on 220V/3Hp induction motor system
