| Summary: | 碩士 === 健行科技大學 === 電機工程所 === 103 === This paper is about conversion for digitizing grid-connected fuel cell power system research. Use green energy power with digital signal processor (TMS320F28335) as the generation system in order to protect environment, also use simulate software (PSIM) to construct a model for boosting the converter and the full-bridge inverter, and discuss each correlative value and works.
The generation system is by 1.2kW proton exchange membrane fuel cell, and the boost converter is by a MOSFET controlling. DC38V boosted DC200V through the converter; the converter used of four IGBT as an inverter controller, output AC110V with grid-connected. The MOSFET and IGBT output PWM and SPWM via digital signal processor (TMS320F28335), this grid-connected efficiency is over 72%. Also join the islanding detection, so when the grid-connected failure, it can suspend supplying grid-connected. Digital signal processor achieved digital data processor and system implementation; fuel cell as grid-connected power, it conforms today’s information and digital green energy, concept of protecting environment and sustainable development.
