Buck Topology Powered Exclusively by Supercapacitor Modules—A Battery-Less Design Concept

Abstract: In this paper, we have shown a DC-DC buck converter design, using two supercapacitors only as power sources. This design eliminates the use of a battery. Here one supercapacitor supplies the positive and the other one supply the negative voltages for powering up all the converter components and for the PWM circuit. The PWM generates a duty cycle, which changes with time to keep the output voltage constant. This output voltage changes due to the continuous voltage drop of supercapacitors modules and due to the … Show more
