Abstract
An insulation type step-up converter includes a core, first and second primary-side coils, a secondary-side coil, and a switching element. The core includes a middle leg, and first and second outer legs. The switching element is configured such that it can be controlled to be on/off so that electric currents flowing simultaneously in the first and second primary-side coils are opposite in direction to each other.
