Abstract: This paper presents the rectifier and inverter part of the design and development of converter for fuel cell system integration. 5KW fuel cell system has DC output voltage of 100V at no load and 60V at full load. The objective of this project is to design a converter system to boost the voltage and produce an output ac voltage of 400V line to line at 50Hz suitable for integrating with grid .The rectifier is used to convert the square waveform at 330V into digital current at 660V. And the inverter is used to invert the 660V digital current into ac voltage of 400V line to line at 50Hz suitable for integrating with grid. The rectifier and inverter is designed depend on the theory. The inverter is a three-phase voltage source inverter. The input of the rectifier is square wave which is chopped and transformed by the inverter and transformer designed by ZhaoYing. According to the design requirements, the maximum voltage of the diode is 330V. Two rectifiers is parallel connection and each is a single-phase uncontrolled bridge rectifier. In order to output 660V DC power into the inverter, one port of the capacity should connect ground. IGBT is used in the inverter and the switches are controlled by the PWM wave. The characteristics and performance of the inverter are tested and analyzed by simulation on PSIM.
