Abstract
Since the discovery of Electricity, we have sought effective methods to store that energy for use on demand. Energy efficiency is “using less energy to provide the same service”. A capacitor can store maximum energy with respect to input by using direct charging method. In this paper four steps charging of capacitor by consecutively changing the duty cycle of Buck converter. In four step charging, dissipation energy is reduced to one 4th when compared with the conventional direct charging. The reduced dissipated energy is verified by MATLAB simulations and by breadboard experiment with help of Micro controller, which an energy reduction of one fourth is confirmed from the measured power supply currents in four step charging.
