Nov. 20, 2009 - Simulating a 5kW Aircraft Power System

Do you work with transformers that have more than two windings? We put an example online, see screenshot and online simulation below, where a 3-three phase interphase transformer is employed.

The rectifier in this example is an interesting topology for aircraft power systems with typical input voltage [98V ... 132V] and a mains frequency [400Hz ... 800Hz]. It's an amazing converter with no active switches (no control electronics) but approximately sinusoidal input currents. You can find more detailed information in this paper.

One can build all types of transformers in GeckoCIRCUITS with the element 'Magnetic Coupling k'. If you have three (or more) windings on a core - like in the example - you need to define one coupling for each inductor combination. This is flexible but often inconvenient. We plan to add a transformer library to GeckoCIRCUITS in a next release.
