Abstract
A DC-to-DC converter. The converter has three inductors, two capacitors, a first switch and a second switch, a first rectifier and a second rectifier, and a transformer with a primary winding and a secondary winding. The first switch and the second switch are turned on alternately according to a controlling signal, and a current may flow through the primary winding of the transformer, thereby transferring energy to the second winding. The first rectifier and the second rectifier operate according to the energy transferred from the primary winding to obtain a solid current through the third inductor, and a solid DC output voltage is output to the load.
