ABSTRACT:
A hybrid electrical generator (20) is disclosed. The hybrid electrical generator has a permanent magnet generator (22) having a permanent magnet rotor (32) mounted on a shaft (26) with the permanent magnet generator providing an output voltage over an operating range which falls in response to an increasing electrical load. The hybrid electrical generator has a variable reluctance generator (24) having a rotor (34) mounted on the shaft with excitation of a stator (30) being provided by the permanent magnet generator. The variable reluctance generator provides an output voltage which varies in response to an increasing load over an operating range. A voltage regulator, responsive to the electrical outputs of the generators, controls the output voltage of the variable reluctance generator to provide a regulated output voltage which is substantially constant independent of electrical load over an operating range.
