Analysis-intelligent design and simulation of improved state–space modelling for control of Luo converter

DC–DC converters are commonly used in industrial drives. A positive-output elementary super lift Luo converter (POESLLC) provides efficient output compared to the conventional DC–DC converter. The control strategy is developed by considering the effects of source resistance and variation in the non-linearity of the inductor and capacitor during charging and discharging periods by performing state–space average modelling for POESLLC. The developed transfer function for POESLLC is analysed by various duty cycles, inductor values, and capacitor values. The pole–zero map indicates that the system is unstable. A compensator and a proportional integral derivative (PID) controller are designed for the stable operation of the system. It is found that the use of a compensator provides better settling time as compared to the PID controller.
