Design of hybrid boost converter for PV applications

In recent years, DC-DC converter plays a vital role in many applications such as EV, PV based systems etc. Hence, the designed converter should exhibits high voltage gain ratio and higher efficiency. Thus, this work proposed a new topology of DC-DC converter with soft switching. This proposed converter is based on coupled inductor and it integrates both boost and switched capacitor based fly back converter. In the flyback configuration, it includes SC network so as to enhance the voltage gain.To improve the dynamic response of the converter, Proportional, Integral and Derivative (PID) controller is implemented. However, the linear controllers are influenced by the system parameters of the converters, it results in reduced voltage regulation for wide variations in system parameters. Hence to overcome this, ANFIS controller is employed to provide voltage regulation. The performance of the proposed controllers is validated using both simulation and experimental results. From the results, it is revealed that the proposed converter is a viable alternative to PV applications.
