Dynamic evolution control of interleaved boost dc-dc converter for Fuel Cell application

An electric vehicle powered by the fuel cells called Fuel Cell Electric Vehicles has higher efficiency and lower emissions compared with the internal combustion engine vehicles. In this application, a high power boost dc-dc converter is adopted to adjust the output voltage, current and power of fuel cell engine to meet the vehicle requirements. The major challenge of designing a boost converter for high power application is how to handle the high current at the input and high voltage at the output. In this paper an interleaved boost dc-dc converter is proposed for stepping-up the voltage on high power application. The controller of converter system was designed. A new approach for interleaved boost converter controller based on dynamic evolution control theory is presented. Performance of the interleaved boost converter with the proposed dynamic evolution controller is tested through simulation.
