| Summary: | 碩士 === 國立高雄第一科技大學 === 電子工程研究所 === 101 === This paper presents the design of a family disaster prevention type fuel cell power supply system, this system architecture is to use the fuel cell provides power, high step-up circuit structure utilizes the boost-flyback converter based derived to boost-forward-flyback converter, through the full-bridge converter switching DC to AC used to supply the family. This system with hydrogen as the fuel supply electricity, and the supply of electricity will not cause environmental pollution, it’s very environmentally friendly. When emergency or disasters can provide basic and essential power of the family. Finally, the implementation of the circuit specifications of the input voltage is 80 V , the output voltage of 380 V and a rated power of 1000 W high booster circuit, and digital controller dsPIC30F4011 as the full-bridge converter of the power switch control, final experimental results of the output AC 60Hz , 110V to verify the effectiveness and practicality.
