Project Code :TEPGPS620


The main objective of this project is, controls the grid current by regulating the rectifier current sixth harmonic for Three-Phase Diode Rectifier-Fed Small DC-Link Capacitance IPMSM Drives


In order to improve the grid current quality of the small dc-link capacitance (SDC) motor drives fed by three-phase diode rectifier, a grid current control method based on regulation of the rectifier current sixth harmonic is proposed in this paper. Considering the 120° maximum conduction angle of the rectifier diodes, a 120° rectangular waveform with low total harmonic distortion (THD) is selected as the grid current reference. Based on the relationship between the grid current and the rectifier current, the proposed scheme shapes the grid current into the selected 120° rectangular waveform by regulating the rectifier current sixth harmonic.

Index Terms--Diode rectifier, electrolytic capacitor-less, grid current harmonics, interior permanent magnet synchronous motor (IPMSM), motor drives.
