A Simplified Output Feedback Controller for the DC-DC Boost Power Converter

Boost-type dc-dc converters present non-minimum phase dynamic system characteristics. Therefore, controller design using only the output voltage for feedback purposes is not a very straightforward task. Even though control can be achieved inductor current control, implementation of such current-mode controllers may require prior knowledge load resistance and also demand more states as one or currents in feedback. In this paper, development new boost-type presented. The form that it avoids possibility saturation signal due to division by zero. basic structure proposed firstly obtained from expression open-loop signal, complete then derived satisfy closed-loop stability conditions. Simulation experimental results clearly verify ability law provide robust regulation against parameter variations.
