Using Power Electronics to Increase Performance and Extend the Applications Range of a Single-Phase Induction Machine

This paper presents a simulation model of a single-phase induction machine (SPIM) in the split-phase and start-run-capacitor operation modes, in order to compare performance characteristics of these machines. The run capacitor is sized to mitigate torque pulsations at one operation point. Furthermore, in order to reduce these pulsations regardless of the operation point, it is proposed to feed the auxiliary winding of the SPIM with an electronic converter. This paper also investigates a variable speed drive based on the SPIM using field-oriented control
