Abstract
The present research work proposes a photovoltaic energy harvester and an appropriate direct current (DC)/DC converter for a harvesting system after the study of the devices and taking the operation conditions. Parameters such as power, efficiency and voltage are taken into account under different environment conditions of illumination and temperature in order to obtain the best possible response. For this reason, suitable metal-oxide semiconductor field-effect transistor (MOSFET), diode, coil, frequency, duty-cycle and load are selected and analyzed for a DC/DC converter with boost architecture.
Highlights
Nowadays, low-cost, smart electronic systems and wireless sensor network technologies are experiencing fast growth
If input/output power is taken into account, the simulation results show that the most suitable value for the coil is 200
Energy harvesters are being increasingly used for gathering energy from the environment and efficiency is 94.03%, and occurs at 0.5 sun and 15 ◦ C; and the lowest efficiency (92.30%), is obtained at
Summary
Low-cost, smart electronic systems and wireless sensor network technologies are experiencing fast growth. The converter of aaharvester be adaptedand to the energy andprovide waveforms that its collect energy in AC form, while few, suchmust as photovoltaic thermoelectric It requires specific research on each of the elements that constitutes. This research is devoted a complete energy work harvester [14,15].to the characterization, modelling, design and parametrization of DC harvestersmodelling, and theirdesign required power converter. On the previous model for the energyand harvester, a photovoltaic cell, is defined and Based analyzed through and results, mixed the DC/DC converter architecture is selected. The research endspassive with a statistical and analysis of the converter architecture taking in account parameters as power, efficiency, voltage and current performance of the state-of-the-art passive and active devices within the DC/DC converter waveforms. Results obtained are used efficiency, to identifyperformance the most suitable arrangement of discrete components for maximum efficiency, performance and given by the DC/DC converter architecture
