In this paper, the single-phase operation of a permanent-magnet induction generator (PMIG) is analyzed theoretically and experimentally and is compared to that of a conventional induction generator (IG) of the same size to evaluate its usefulness. Phase balancing is achieved by connecting a phase converter across their stator windings. Based on the method of symmetrical components, the steady-state performance of both the PMIG and the IG is theoretically predicted, and the results are verified through experiments. The PMIG exhibits a higher performance, in terms of output power, power factor, and efficiency, than the conventional IG.
