In the era of proliferated distributed renewable energy sources, high-gain DC–DC converters dragged much attention among the researchers. But there is a concern that high-gain converters have less efficiency and high switching stresses. The converter topology has two quasi-impedance source network and a voltage multiplier cell unit to facilitate very high-gain output voltage. This work also suggests using a non-linear carrier controller which embodies two loops within it: one facilitates the input variations and the other loop assists load regulations. The input variations due to varying irradiation of photovoltaic are alleviated by employing the perturb and observe maximum power point tracking mechanism. The simulation of the work is realized in MATLAB/Simulink arena, and hardware circuits are validated using the dsPIC30F4011 controller. This paper proposes a new two-loop control embedded high-gain DC–DC converter fed by photovoltaic source which aims at encouraging the project-driven engineering education teaching and thereby inherently complying to the standards set for academic excellence through Bloom's taxonomy.
