Abstract


Objectives: The paper presents design and analyze of PV based Super-lift Luo converter with different controllers in the modern technology of DC-DC converter. Methods: The Luo converter provides output voltage which is positive from positive source voltage. By using this converter power density obtained is high with less ripple content in voltage and current profile. It is proven from the Mathematical modeling that the output voltage increases in geometric progression, thereby efficiency of the converter increases. The controller parameters in PI controller are tuned using Ziegler Nichols tuning algorithm. The paper proposes a design of hybrid controller which gives good transient performance compared with conventional PI controller. Findings: Using Simulink the proposed converter with its control circuit is implemented. The main advantage of this proposed converter based on photo voltaic system is that it produces voltages increasing in geometric progression. The converter has proved to be robustness around the operating point. In various operating condition, the dynamic performance with input voltage variations and load fluctuation is good. The simulation performance closely coincides with the theoretical analysis. The settling time and overshoot obtained using hybrid controller is compared with fuzzy controller and conventional controller and it is proven that hybrid controller has good dynamic performance. The real time implementation with solar PV cell is also carried out. Applications/Improvements: The converter finds wide application in switch mode power supply and speed control of DC motors.
