Modified Boost Converter for High Power Applications

Lithium-ion battery is one of the competent sources for electric vehicle. In this work, the lithium-ion battery is integrated with Multiphase Boost Converter and is compared with conventional boost converter. The proposed method is tested on software and hardware platforms in order to test its efficacy. The comparison is done on the basis of maximum duty ratio, size of inductor and source ripple current. The results show that the size of inductor get reduced to half to that of conventional boost converter. The proposed system will reduce the ripple current coming to the source and increase the power transfer from the source to the load.
