Abstract
Abstract By utilizing, in a hybrid (electrical-heat engine) vehicle an alternator which is totally free of elemental iron in its magnetic circuit, the alternator (with appropriate rectification means) can be connected, selectively, in series, parallel or in lieu of the storage battery pack for activating the electrical motor which drives the wheels of the vehicle or any other load mechanically coupled to the electrical motor. Quick surges of power can thus be delivered to the load to achieve, for example, rapid acceleration of a vehicle.
