The paper presents a new scheme for the efficient generation of high electric power, demanded for future automobiles. The new system, consists of a permanent magnet (PM) alternator having high energy MAGNEQUENCH (MQ) magnets and split winding; and a novel electronic voltage regulation scheme. A proof of concepts system, capable of providing 100/250 A (idle/cruising) at 14 V has been built and tested in the laboratory with encouraging results. The high output is provided at 15-20 % points higher efficiencies than conventional automotive alternators, which translates into considersable fuel economy savings. The system is 8 dB quiter and has a rotor inertia of only 2/3 that of an equivalent production alternator, thus allowing for a belt drive without excessive slippage.
