Analytical Derivation of Output Distortions Harmonics Caused by Voltage Source Inverter Non-Linearities in PMSM Drives
Résumé
This paper presents a new direct analytical derivation of low frequency harmonics introduced by voltage source inverters non-linearities in PMSM drives. The proposed voltage drops model is robust and requires fewer calculations than time-based models, and has proven to accurately estimate the experimental voltage drops for SiC based inverter output waveforms. Furthermore, it has been extensively validated experimentally and offers an analytical tool to precisely estimate the voltage drops introduced by the inverter non-linearities.
