碩士 === 國立高雄應用科技大學 === 電機工程系博碩士班 === 104 === A distributed PV control architecture, which the DC-DC converter is moved from the inverter to solar panel array end, is not only can to improve the overall efficiency of power generation, but also can to simple the inverter design, to reduce electromagnetic interference EMI and implementation costs, to extend service life of many other benefits and so on. The main purpose of this thesis is to develop and to simulate boost converter as a voltage regulator which can mounted on the distributed PV systems. This proposed converter can maintain each loop in the same parallel bus voltage level during abnormal period, and then to improve the output efficiency of the PV system. The main approach is to use PSIM simulation software to build the distributed PV system and to simulate the models in two status. One status is that every circuit has regulator to control output voltage and the other status has no. On the other hand, to develop a 5kW high-power level boost converter which can be applied to the proposed PV system, in order to verify the actual circuit performance testing and the availability.
