ABSTRACT:
A current regulator for a four-legged, three-phase inverter determines the next optimal, or near-optimal, inverter state in a relatively short time period based on phase current error signals and back-emf's, resulting in low harmonic distortion, reduced current ripple, minimal current stresses, and increased utilization of the available dc bus voltage over a high bandwidth.
