| Summary: | A new model of switch inductor (SL) combined
with a voltage doubler-employed DC-DC step-up converter has
been developed here to get optimum output from the solar
photovoltaic cell. The voltage transformation ratio of the
proposed circuit is almost six times higher than the input
voltage. The high step-up ratio is obtained without worsening
the transformation efficiency of the converter. The
functionality of the suggested configuration has been compared
with current, advanced DC-DC converters incorporated with a
PV source. The proposed design performs better than existing
designs regarding voltage gain and efficiency. Maximum
Power Point Tracking (MPPT), an approach that relies on the
Perturb and Observe (P&O) algorithm, has been used to
ensure the optimum performance attainable from Photovoltaic
panels. The employment of MPPT controllers does not
deteriorate the performance of the proposed design; instead,
96% conversion efficiency has been achieved. Simulation of the
proposed and existing topology have been carried out in PSIM
and Simulink environments. |
