Aerospace Electrical Voltage Level definitions
It is the expectation that for electric propulsion even higher voltages in the range of 1 - 3 kV and higher are needed. The introduction of hybrid or electrical propulsion, will also affect the system architecture of the electrical power system. This report shall set forth the aerospace voltage level definitions.
Rationale: It is expected that future aircraft programs will become more electric, with possibly hybrid or electrical propulsion, resulting in higher electrical loads. This will require other voltage ranges. New candidate supply voltages could be 0-270VDC, ±135VDC, ±270VDC, 0-540VDC or even higher. This report shall set forth the voltage level definitions as discussed in the AE-7 committee.
