New Aircraft Power System Design Studies

This paper frames the power supply scheme of Low Voltage Director Current and Variable Speed Constant Frequency (VSCF) for the Bomb six aircraft. Then some detail research and circuit design is made to some key section of the VSCF power.First of all, capability of the aircraft power supply and load analysis is done, get two different main power supply scheme, then the two scheme is compared them and the better one is selected.To VSCF, the regulation thesis analysis and converter main circuit has been finished. In the former, circuit of regulation such as voltage and current sense, control and feedback circuit are all discussed. At latter, methods of confirm part parameter in the converter is introduced, most parts of 3-phase rectifier and filter, inverter and filter, NFT are confirmed.Furthermore, simple simulation model of VSCF and the simulation results are presented. It shows the system is stable and calculated some guideline.
