Abstract

This project is to simulate and to design a DC-DC switching boost converter for current ripple reduction. Step up converter is also referred to boost converter where its characteristic is to have a voltage at the output that is larger than the voltage at the input. The converter operates by opening and closing an electronic switch such as a power MOSFET, IGBT’s or thyristors periodically. Ripple exist during the switching process in the DC-DC converter where the change or switching from the ON state and OFF state produces current ripple in the inductor. By reducing the current ripple in the DC-DC switching boost converter, the efficiency of the DC-DC switching boost converter will increase. Methods that is available for current ripple reduction includes by increasing the value of the inductor, by using soft-switching techniques and also by the adaptation of interleaving technologies. The method of varying the value of inductance to reduce the current ripple in the DC-DC boost converter is presented in this paper. Keywords: DC-DC converter, boost converter, current ripple, reduction
