High Voltage Gain Interleaved DC Boost Converter Application for Photovoltaic Generation System

摘要

This paper presents a novel high voltage gain interleaved DC boost converter. This converter is non-isolated boost converter, which can level up DC voltage from 24 Vdc input voltage to 130 Vdc output voltage. This is adequate suitable in order to develop and apply with any dc output renewable energy source, such as PV generation system and etc. The converter in this paper has power rating at 350W. The proposed converter has totally four modules of DC boost converter, which are connected in parallel. At the same purpose, these switching devices are controlled by 90 degree shifting to each other, due to an interleaving technique. This will leads to a smoother output dc current. Nevertheless, the High gain DC boost converter in this project was done by MATLAB / SIMULINK based Digital Signal Processing Board (here is TMS320F2812) implementation. The laboratory experiment shows that the converter works very well, and its result is in a good satisfaction.
