To cancel harmonics and get fundamental back EMFs for precise rotor position and speed estimations under short-circuit (SC) fault, this article introduces a new sensorless fault-tolerant control method for 5-phase PMSM using a sigmoid sliding mode ob

Dynamic voltage restores (DVRs) are usually used to mitigate the effect of voltage sag and guarantee sufficient power supply for sensitive loads. However, three-phase voltage cannot be compensated to the desired balance voltage under unbalanced three

Given the problems that the phase-locked loop frequency coupling effect (PLL-FCE) in a weak grid reduces the quality of the output current waveform and brings challenges to maintaining a steady running of the grid-connected converter (GCC), this pape
