Analysis of System Interharmonics of VSI-Fed Small DC-Link Drive with
Small dc-link drive is a research focus in the past years, due to its compact size and improved reliability. However, the small dc-link drive with diode rectifier may suffer from resonance between the system input inductor and the dc-link capacitor, which will result in unacceptable grid current harmonic distortion. Various passive- and active-damping …
