Abstract
A power distribution system includes a variable frequency alternating current (AC) generator, an active rectifier electrically connected to the variable frequency AC generator such that AC power output from the variable frequency AC generator is rectified by the active rectifier, and a switching controller configured to detect a fundamental frequency of the AC power output and lock an active switch rate of the active rectifier to an integer multiple of the fundamental frequency.
