Design and Analysis of Five-phase and Three-phase Combined Dual Winding Induction Generator for Integrated AC/DC Generating System

Dual winding induction generators (DWIGs) are well-suited for high safety applications, such as more-electric aircraft (MEA). This paper presents a comprehensive design and analysis of a five-phase and three-phase combined DWIG with a rated speed of 12300r/min for integrated AC/DC generating systems. Unlike conventional three-phase generators, the proposed DWIG features two distinct sets of windings, with a five-phase winding employed on the control winding side and a three-phase winding on the power winding side. The designed DWIG configuration effectively caters to the demanding operating conditions of integrated AC/DC generating systems. This study provides a detailed introduction to the topology and design characteristics of the generator. Additionally, the electromagnetic performance of the DWIG is investigated using finite element simulations under aviation generating modes. The results demonstrate that the proposed DWIG exhibits reduced torque ripple, enhanced fault tolerance, and increased reliability, making it a promising solution for integrated AC/DC generating systems.
