This paper describes an ultra high-speed permanent-magnet synchronous motor drive, which is embedded in a turbocharger of an internal-combustion engine. The electrical drive makes it possible to enhance output power of the turbocharger in a motoring mode and to retrieve combustion energy from exhaust gas in a regenerating mode. Computer simulations and experimental tests are conducted to examine various operation characteristics of a prototype. The experimental data demonstrate 220000-r/min operation at 2.2-kW inverter output power, which agree with the simulation results well and prove feasibility of the proposed system.
