Step up DC-DC converter based on three winding coupling inductor

Abstract

This paper presents the new topology for DC-DC converter based on three winding coupled inductor that boosts the voltage. This topology includes high frequency coupled inductor and voltage multiplier cells[1]. The main aim is to increase the voltage gain. The output voltage is clamped across the capacitor of Voltage Multiplier Cells (VMC). Only one active switch is used which is MOSFET. The voltage stress is decreased and overall efficiency is been improved. The quantity of diodes can be diminished by expanding the quantity of auxiliary windings of coupling inductor. The spillage inductance of the coupled inductor is reused by exchanging capacitor and can be straightforwardly exchanged to stack.
