A permanent magnet fault tolerant generator 32 is driven by a variable speed shaft 34 to create AC power at terminals 36 , converted at 40 to DC power before being applied to a load 38 . The converter 40 is a bi-directional device which rectifies AC to DC and also acts as an inverter to synthesize AC from the DC. This synthesized AC waveform is imposed on the terminals 36 to maintain a constant magnitude generator output voltage, regardless of the speed of the shaft 34 , and thus regardless of the EMF of the generator. This results in reactive currents f...
1. An aerospace generator arrangement operable to provide DC power from a rotating member, the arrangement having a permanent magnet generator driven, in use, by the rotating member to provide AC power at the output terminals of the generator, converter means operable to convert the AC output to provide DC power at substantially constant voltage, and control means which, in use, maintain constant magnitude AC voltage at the generator output terminals, regardless of the generator EMF. 2. An arrangement according to claim 1, wherein the generator is fault ...
