Abstract
A conversion apparatus with oscillation reduction control includes a conversion circuit and an oscillation reduction control circuit. The conversion circuit includes a transformer, a rectifying circuit, and a first switch. The oscillation reduction control circuit stores a leakage inductance energy of the transformer when the first switch is turned off, and the oscillation reduction control provides the leakage inductance energy to a primary-side winding of the transformer when the first switch is turned on.
