Abstract

This paper introduces electrically assisted turbocharging (EAT) together with the requirements and challenges in selecting an electrical machine for the application. In an effort to identify the most appropriate technology, a detailed, quantitative, multidomain comparison between induction, permanent magnet, and switched reluctance machines is conducted. The study presented puts equal weighing on the electromagnetic, thermal, and mechanical sciences, together with the all-important cost and provides clear guidelines on the pros and cons of each machine type for the application in hand. For a real case study, the induction machine (IM) is identified as the most suitable candidate due to its high-temperature withstand and equalizing capabilities, together with the lower volt-ampere (VA) requirements. A high-performance (10 kW, 120 krpm) IM is prototyped and specific suitability aspects demonstrated on actual system-representative tests.
