Interharmonic Mitigation Using Boost Converter In Variable Speed Drives
Publication Date : 23/04/2016
Voltage source inverter (VSI) fed induction motors are widely used in industries. It injects significant amount of harmonics and interharmonics into the supply system. Interharmonics are components whose frequencies are not an integer multiple of the fundamental frequency. Interharmonics are injected into the supply when two different frequency systems are interlinked or due to load unbalance. In this work motor load unbalance is considered and a boost converter is designed to mitigate interharmonics. Simulation is carried out in PSIM and the superiority of the proposed method is discussed.
