Abstract
Use of a common electrical power bus to which a number of electrical power generators and consumers are coupled is well known. Typically, a high electrical capacitance is provided across the bus in order to provide stabilisation in the switching of generators and consumer devices as well as differences in the operational performances of the electrical power generators. Particularly in aerospace applications provision of high capacity electrical capacitors creates problems. By providing a feedback control and an electrical power converter take primary electrical power from an electro-mechanical converter associated with a rotating component of a prime mover, electrical power stabilisation is achieved by applying torque changes through the electromechanical converter to the rotating component of the prime mover such that stored electrical power can then be drawn as required to accommodate transients in electrical power on the bus.
