N2 - A modified fixed current-mode (CM) control for the quadratic boost converter in the presence of an uncertain load resistance is presented. Specifically, the existing CM control law is modified to include an additional proportional action and using a normalized output error in order to achieve improved performance. The extra proportional action helps to improve the relative stability. An approximate stability analysis was carried out to gain some useful insight into the proposed CM controlled system. Also, experimental results comparing the performance of the proposed controller with that of the traditional CM controllers under different operating conditions are presented.
