Abstract
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.
