| Abstract: | The DC voltage generated by fuel cell changes dramatically with the variable loads.To obtain the steady and reliable DC voltage,Power Control Unit(PCU) should be used.The voltage-fed full bridge Phased-shifted ZVS DC/DC converter was chose as the front-end DC/DC converter in fuel cell power system.The main design consideration is proposed,and loss dissipation is calculated.Finally,the experimental results on 5kW prototype validate the analysis mentioned above. |
| Keywords: | fuel cell converter / dissipation analysis |
