Novel Configuration of an Inverter-based Three-phase Induction Generator for Single-phase Load: Comparison to TSCAOI Setup

This paper presents the study of a novel configuration of an off-grid single-phase generator using a three-phase Squirrel Cage Induction Machine (SCIM) by providing the comparison to the existing Two-Series-Connected-And-One-Isolated (TSCAOI) configuration. In the TSCAOI configuration, a single stator winding is used for exciting the generator while the other two windings are connected to load. In the new structure, two of the generator stator windings are excited by two independent sources and the remaining winding provides power to load. This setup allows better control freedom and flexibility. The performance comparison of the proposed configuration and the TSCAOI configuration in open loop is presented in simulation and experimentation. This work contributes to frugal innovation for rural electrification in developing countries.
