Investigation of a Super-Lift Luo-Converter used in solar panel system

Solar power is still inevitably affected by the changeable sunlight and weather condition. Furthermore, if the voltage variation is too large, it will have bad effect on loads or power grid. Super-Lift Luo-Converter has very high voltage transfer gain as well as many other advantages such as high efficiency, simple structure and low cost. A double closed-loop control has the ability to make the output voltage closely track a reference value. Therefore, in this paper, a solar panel power system is designed using the Super-Lift Luo-Converter with a closed-loop control to obtain the desired output voltage. To make sure that the designed system met the design requirements, the simulations were carried out by using PSIM. The simulation results showed that the final output voltage was stable which meant the designed solar panel system could effectively increase the stability of the output voltage.
