Abstract
An assembly includes a converter and a controller. The converter has a winding around a transformer core, first and second switches configured to alternately connect respective winding segments to an input power, and first and second resistors respectively connected in series with the switches. The controller is configured to compare voltages corresponding to currents through the resistors and terminate operation of the converter when a difference between the voltages exceeds a threshold indicative of transformer core flux walking.
