Abstract: After analyzing the whole circuit of proposed BOOST converter we find the double output voltage to input voltage. There are no ripples in output voltage. In this circuit the supply voltage is always in continuous conduction mode, when circuit is running in step up condition. A SEPI C converter is a purely DC-DC converter. Its features are similar to the Cuk converter. A boost converter is a step-up converter and a power converter with an output DC voltage greater than its input DC voltage.

Keywords: BOOST converter, SEPI C converter, DC-DC converter, Cuk converter
