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.
