Abstract
Currently used airborne power systems that require 28Vdc and 115Vac power utilize one of the following approaches: - Two generators, one with a DC output and the other with AC output - A single DC generator with AC a Static Inverter or an AC generator with a TRU Both techniques listed above have weight, size and efficiency impacts to the system. It is, therefore, beneficial to identify a solution that would utilize a single generator with dual output which would require minimum power conversion and conditioning. Such system would offer high efficiency at a low weight, as well as significant cost advantages. IPS is proposing an innovative generator design which will include a second AC winding on its stator in order to provide the AC output. IPS engineers have experimented with this type of generators, and found the idea viable. Dual output, which will yield in essence a 17 kVA generator, will have a small impact on the diameter when compared to an equivalent DC generator with only 400 A output and a small weight penalty, keeping the output a high efficiency. The GCU will have to include a small VSCF converter in order to provide the required AC output.
