Comparative study of current-mode controllers for the positive output elementary Luo converter via state-space and frequency response approaches
This study presents the comparative study of dual-loop current-mode controllers to achieve the output voltage regulation of the positive output elementary Luo (POEL) converter. The POEL converter is a fourth-order dc-dc boost converter developed using the voltage lift technique that gives a positive...

This study presents the comparative study of dual-loop current-mode controllers to achieve the output voltage regulation of the positive output elementary Luo (POEL) converter. The POEL converter is a fourth-order dc-dc boost converter developed using the voltage lift technique that gives a positive load voltage. Two current-mode controllers, one using the input inductor current and one using the output inductor current, are studied. Both state-space and frequency response approaches are used in the study to obtain a better insight of the comparative study. It is demonstrated that the controller using the input inductor current is more suitable for the regulation of the POEL converter. Experimental results showing the features of the controller in the presence of load and reference voltage changes are also provided to validate the theoretical conclusions. |
