Abstract
An alternating current generating system (40) for an air frame producing an output potential in accordance with the invention includes a generator (42) for generating current having a rotor (46) mounted on a shaft (50) which is rotatably driven and a stator (58) from which current is outputted; a variable reluctance generator (44) for generating alternating current outputted from a stator (62) and having a rotor (48) mounted on the shaft to cause alternating current to be generated by the stator and a voltage regulator (84), coupled to the generator for generating current, to an output of (88) of the variable reluctance generator and to an excitation winding (86) of the variable reluctance generator, for producing excitation current applied to the stator of the variable reluctance generator to regulate the voltage outputted by the variable reluctance generator.
