An aircraft power supply for providing DC power with improved power quality characteristics. The aircraft power supply includes a transformer control system that can use closed-loop feedback from a DC power output to control switches that can short primary windings turns of a step-down transformer. By shorting turns in the primary, the transformer control system can control or manipulate the turns ratio in the transformer and compensate for decreases in the DC power output.

Aircraft power supply and method of operating the same

An aircraft power supply for providing DC power with improved power quality characteristics to the aircraft. According to one embodiment, the aircraft power supply includes an input filter, a step-down transformer, one or more rectifier networks, and an output filter with a voltage modulation attenuator to passively improve power quality characteristics. The voltage modulation attenuator may use a certain arrangement of inductors, capacitors and diodes to reduce voltage transients in the aircraft power supply.
