Abstract
Primary and secondary currents of a converter transformer in a double-ended converter are continuously monitored to detect the onset of saturation in the magnetic core of the transformer. When the onset condition is detected, the conductive roles of the oppositely phased switching transistors in the converter are reversed to limit and counteract the onset of saturation in the magnetic core of the transformer.
