This paper proposes a power factor control strategy for a current source drive with active front end, where the selective harmonic elimination (SHE) modulation is employed for the rectifier and a combination of space vector modulation (SVM) and SHE is used for the inverter to guarantee best waveforms at a low switching frequencies. The proposed power factor compensation strategy comprises two methods:...
In this paper, a loss reduction and DC link current minimization strategy for a high power current source inverter (CSI) fed drive is proposed. The proposed strategy consists of an inverter maximum modulation index control scheme and a flux optimization algorithm. Specifically, in the inverter modulation index control, the CSI modulation index is kept at the maximum value while the current source...
