Abstract: A multi-phase AC-DC aircraft power converter having an input filter, power transformer, rectifier, output filter, and dummy load that provides improved voltage regulation across a range of output current loads. The transformer includes a primary and a pair of secondary windings. The input filter receives multi-phase AC input power and is connected to supply filtered input power to the primary of the transformer, with the secondary windings being connected to the rectifier. The rectifier provides a DC output that is connected to the output filter. The dummy load is connected at the output filter and is designed to draw sufficient current from the DC output such that the converter operates at a substantially linear I-V characteristic across a range of loads extending from a low load of less than 5 Amps to a high load of greater than 50 Amps.
