Output Voltage Regulation for Negative Output Elementary Super Lift Luo Converter Using PI Controller Parameters Setting
This paper studies an output voltage regulation for Negative Output Elementary Super Lift Luo Converter (NOESLLC) operated in Continuous Conduction Mode (CCM) using Proportional-Integral (PI) controller parameters setting. The NOESLLC performs the voltage conversion from positive DC source voltage to negative DC load voltage. In order to improve dynamic performance of NOESLLC for both static and dynamic specifications, we propose a PI controller. The parameters value of the PI controller is computed based on the Ziegler-Nichols method – 1 tuning design procedure. The PI controller is designed by using state-space average modeling of NOESLLC. The simulation of NOESLLC with its control model is implemented in MatLab/Simulink. The static and dynamic performances of the system are tested at various regions. A simulation results validate the effect of the parameters value of PI controller on the static and dynamic performances of the NOESLLC, which is applicable for common DC-DC conversion purpose, computer power supplies, communication equipments and medical equipments.
