In this article, a high step up DC-DC Converter which is integrated with renewable energy resources is proposed, which uses flyback converter to obtain high static voltage gain to improve the efficiency of the converter by reducing the voltage stress across the switch and diodes.Abstract:
In this article a high step up DC-DC Converter which is integrated with renewable energy resources is proposed. The disadvantage of conventional converters is that it has high duty ratio and high voltage stress across power devices with less efficiency. The proposed methodology uses flyback converter to obtain high static voltage gain to improve the efficiency of the converter by reducing the voltage stress across the switch and diodes. Thus by avoiding the operation of the high duty ratio and recycling of coupled inductor stored energy, the overall efficiency of the converter gets improved.read more
