Abstract
Fuel cells are a potential power source for electric vehicle or distributed power generation system. Fuel cells have several advantages such as low emission, direct energy conversion, quiet operation, and size flexibility. An electric vehicle powered by the fuel cells, FCEV, has higher efficiency and lower emissions compared with the internal combustion engine vehicles. In this application, the high power dc-dc converter is required to adjust the output voltage, current and power of fuel cell to supply the vehicle requirements. Due to the output voltage of fuel cell is rather low than the dc bus voltage, a high voltage ratio boost dc-dc converter is required as interface to convert the low dc voltage of fuel cell into a sufficiently high voltage dc-link bus voltage. At the same time for high power applications such as electric vehicle, the low input voltage causes the input currents that flow becomes very large. This research proposed a new topology of high voltage ratio boost dc-dc converter with interleave and cascade technology for fuel cell application. The proposed interleaved boost dc-dc converter have been designed and developed. An approach for interleaved boost converter controller'™s synthesis, based on dynamic evolution control theory is explored.

Current Problem/Background
Recently, the application of fuel cells as a clean renewable energy is increased. Fuel cells are a potential power source for electric vehicle or distributed power generation system. Fuel cells have several advantages such as low emission, direct energy conversion, quiet operation, and size flexibility. An electric vehicle powered by the fuel cells called Fuel Cell Electric Vehicles (FCEV) has higher efficiency and lower emissions compared with the internal combustion engine vehicles. In this application, the high power dc-dc converter is required to adjust the output voltage, current and power of fuel cell to supply the vehicle requirements. Generally, the output voltage of fuel cell is rather low, while the motors are driven at higher voltages. Hence, a high voltage ratio boost dc-dc converter is required as interface to convert the low dc voltage of fuel cell into a sufficiently high voltage dc-link bus voltage. At the same time for high power applications such as electric vehicle, the low input voltage causes the input currents that flow becomes very large. This research proposed a new topology of high voltage ratio boost dc-dc converter with interleave and cascade technology for fuel cell application. The proposed interleaved boost dc-dc converter has been designed and developed. An approach for interleaved boost converter controller'™s synthesis, based on dynamic evolution control theory was explored. As a result, a new high voltage ratio interleaved boost dc-dc converter for high power fuel cell application has been produced.
