Loss Reduction in V/f Control for Switched Reluctance Motor Driven by Single-Pulse Voltage

This paper proposes a single-pulse drive method in V/f control, which consists of two original approaches and one modification: (i) generation of a single-pulse voltage with a zero-voltage period, (ii) correction method for a conduction period error due to a discrete control system, and (iii) modification of the high-efficiency control to specialize in single-pulse voltage drive. The proposed method reduces of 11.7% of the copper loss and 19.2% of the iron loss in the experiment.
