Design of a High Step-Up Interleaved BoostConverter with PI controller

Abstract

Generally conventional boost converters have been used to obtain higher output voltage than the input voltage. When these boost converters are operated for high ratios it leads to high voltage and current stress on the switch. Hence an interleaving technique of boost converter has been presented. This method of approach can be used in high power applications to produce high voltage gain when compared to the conventional boost converter. This project report deals with the simulation of Interleaved Boost Converter (ILBC). It is seen that, for higher power applications, more modules can be paralleled to increase the power rating and the dynamic performance. One of the challenges in designing a boost converter for high power application is how to handle the high current at the input side. In this project report an interleaved boost dc-dc converter is proposed for current sharing on high power application. Moreover, this converter also reduces the ripple of voltage. The simulated results are presented with R load.
