An observer based analysis is carried out to improve the dynamic responses of the super lift Luo converter with positive output voltage along with a digital controller. The dynamics of the closed-loop system is investigated using discrete time modeling technique which includes the dynamic compensation in the form of prediction observer controller for obtaining output voltage regulation. The implementation which includes the digital state feedback and a load estimator is very simple and well-suited for the digitally controlled PWM converters. A suitable feedback matrix and a load estimator are selected to eliminate the error and to estimate the unmeasurable state variables. Thus we can obtain zero output voltage error, stability, robustness and stiff voltage regulation at the output. The feasibility and functionality of the discrete system are verified using simulation and experimental prototype of digitally controlled PWM superlift Luo converter.
