ABSTRACT: This paper proposes the new cascaded series
parallel design for improved dynamic performance of DC-DC buck boost converters
by a new Sliding Mode Control (SMC) method. The converter is controlled using
Sliding Mode Control method that utilizes the converter’s duty ratio to
determine the skidding surface. System modeling and simulation results are
presented. The results also showed an improved overall performance over typical
PID controller, and there was no overshoot or settling time, tracking the
desired output nicely. Improved converter performance and robustness were expected.
