Abstract
Disclosed herein are a DC-DC boost converter circuit, which is capable of preventing power loss and stabilizing switching elements by implementing soft switching and improving efficiency by adding a charge pumping function, and a method for driving the same. The DC-DC boost converter circuit, in which an inductor and an output diode are connected in series and an output capacitor and a load are connected to an output port of the output diode in parallel, includes an output stabilization circuit in which first and second switching elements, a transformer, a plurality of boost capacitors, and a plurality of diodes are connected in series/parallel between the inductor and the output diode.
