Abstract
An AC/DC power converter has, as its first stage, a capacitor divider and rectifier and, as the second stage, a switch mode power supply. This configuration may be suitable for low power low voltage aerospace applications. The benefits of the circuit may include small reactive component size; near sinusoidal input current, low EMI emissions resulting from low inrush current; intrinsic current limiting that may eliminate the need for short circuit protection; and low overall component count.
