Abstract :
This paper presents the design of nonlinear dynamic control for switching a current-mode DC/DC boost converter by self-inductor current feedback. The proposed control algorithm is implemented on a SAB C167CR microcontroller to regulate the output voltage, provide an optimal of multiplied gain of inductor current feedback for keeping the system adequately remote from the first bifurcation. In spite of nonlinear characteristics and instabilities of the converter, the performance of the closed-loop control system can be considerably improved to avoid bifurcation phenomena. Experimental results show that the technique introduced in this paper gives satisfactory results with the regulating modes in various operating conditions
