Design of low cost power Converter system for fuel cell

This paper studies the design of DC-DC Converter to convert low-voltage energy sources generated from renewable power like battery power, photovoltaic power, or fuel cells into high-voltage ones. The circuit topology of H-bridge converter to convert input voltage, 24 V, into out voltage, 270 V, was realized through applying phase shift angle control so as to manage electric power and voltage in the output side. The advantages of the converter system suggested are the low cost as well as current stress reduction, high efficiency, reliability, and simplified maintenance. It is also found that the system is highly useful to produce household electric power.
