A High Gain Cascaded DC-DC Boost Converter for Electric Vehicle Motor Controller and Other Renewable Energy Applications

An impetuous popularity of electric vehicles (EVs) is of great concern in the field of automobile research. Since electric vehicles run through electric motor so it is important to have reliable DC-DC boost converter which can give stable required voltage for the motor controller. In this paper a modified cascaded DC-DC boost converter has been presented. The proposed boost converter can achieve high gain at intermediate duty cycle thereby lowering down the conduction loss, which will be ideal for EVs motor controller and other renewables energy applications. The analysis of the proposed converter is performed both in ideal and non-ideal conditions. The analysis of MOSFET’s junction temperature has also been performed in order to confirm its viability for EV’s motor controller and other renewable energy applications.
