| Abstract |
Fuel cell generators as the distributed generation system with a few hundred watt-a few hundred kilowatt capacity, can supply the high quality electric power to user as compared with conventional large scale power plants. In this paper, PEMFC(polymer electrolyte membrane fuel cell) generator as micro-source is modelled by using PSIM simulation software and DSP based fuel cell hardware simulator based on the PSIM simulation model is implemented. The relation of fuel cell voltage and current[V-I] curve) is linearized by first order function on the ohmic area in voltage-current curve of fuel cell. The implemented system is composed of a PEMFC hardware simulator, an isolated full bridge de boost converter, and a 60[㎐] voltage source PWM inverter. The voltage-current-cower(V-I-P) characteristics of the implemented fuel cell hardware simulator are verified in load variation and transient state and the 60[㎐] output voltage sinusoidal waveform of the PWM inverter is investigated under the resistance load and nonlinear diode load. |
