Chapter 44 Development and Implementation of Synchronous DC-DC Buck Converter for Photovoltaic Power Generation

摘要

This paper presents the development and implementation of non-isolated synchronous DC-DC buck converter for photovoltaic power generation. The intention in designing synchronous DC-DC buck converter is to provide robust maximum power point tracker acting as an intermediate between the photovoltaic module and load. The dead-time interval and bootstrap technique are implemented in this topology. Experimental results demonstrate that the proposed prototype achieved an average of 80 % efficiency with maximum output power of 60 W at a constant input voltage of 20 V.
