Abstract

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 methods have been studied to mitigate the undesired oscillations in the grid current and dc-link voltage caused by the resonance. However, the above studies only focus on constant power load conditions. In this paper, the system performance on periodic varying power load conditions is analyzed. The harmonics and interharmonics at both sides of the dc-link stage are studied analytically. Simulation and experiment results are provided to support the analytical study.
