摘要：
The Wireless Sensor Networks (WSNs) are the backbone of today's modern Internet of Things (IoT) applications like Smart Homes, Smart Buildings and Smart Cities. But, WSNs suffer from a major design limitation of limited battery energy availability. Therefore, we propose a solar-powered DC-DC buck converter for energy harvesting WSN nodes. This buck converter is powered by renewable energy and provides a very good solution to limited battery energy availability of WSN nodes. The Buck converter is a step down DC-DC converter in which harmonics and power losses are very low as compared to the boost converter. In switching regulators, the output voltage ripples depend upon inductor values, capacitor value, MOSFET switching frequency and duty cycle. This paper focuses on the design and analysis of DC-DC converters for low-power Photovoltaic (PV) energy harvesting applications such as WSN nodes. The simulation work is done using MATLAB software. From the simulation results, it is proved that the output voltage ripples are inversely proportional to the value of the inductor, capacitor and duty cycle.
