Modeling and adaptive control of modified LUO converter

Abstract

This study presents the implementation and modeling of adaptive control of a modified LUO converter which eventually result in the progression of the dynamic functioning of power converter. In general, LUO converters include two series, which are major and additional series. DC-DC conversion has been executed to employing LUO converter and fly back converter. It uses VL technique in order that output voltage is intensified in every stage. The most important advantages of the proposed structure are that it has the benefits of the switched capacitor and as well VL technique. PI Controller has been used in order to simulate the experimental set-up. Embedded C programming was employed to create the PI controller set up. Kp and Ki values have been calculated using the Ziegler Nichols technique. Simulation has been done using MATLAB. Boosting has been accomplished using the voltage lifting technique. Findings emphasized that LUO converters are likely to improve the power transfer gain in energy progression. Also, the proposed LUO converter in the research has been proven to be able to provide a topology which eventually lessens the output ripple and losses. To verify the proposed DC-DC power converter performance, the simulation and experimental setup has been tested with certain parameters, including source voltage and current, capacitors, etc. Several forms of LUO converter voltage lifting (VL) methods performance including ultra-lift, re-lift and self-lift have been compared with that of the performance of the proposed design. Comparison between different voltage gains of LUO converter topologies have also been carried out in this research. The results reveal that the proposed design gives better boost in voltage, compared with that of the existing designs.
