Abstract
Soft switching DC-to-DC converter achieves simultaneously ultra high efficiency and very small size owing to a new magnetic circuit structure and a corresponding novel converter circuit configuration with special properties. Unique magnetic design also provides an overload current capability of several times the nominal load current. Despite its simple implementation requiring only proper drive timing of the switching devices, the unique soft-switching methods result in nearly complete elimination of switching losses over the entire operating range. This, in turn, permits operation at even higher switching frequencies, and leads to further reduction in size and weight.
