Abstract

Controlling output voltage of the DC-DC Buck-Boost converter has been a challenging topic for many years, since its averaged dynamics is a non-minimum phase system with highly load variation. Several methods avoid this difficulty by controlling the voltage via the inductor current. This paper presents a nonlinear energy-based controller design approach, which can directly control the output voltage without internal current loop. Due to damping assignment technique, the damping of the closed-loop system can be determined, and the problem with load variation is solved. To verify the performance of the proposed approach, the controller is test with a simulation and with existing converter. The result confirms the achievement of the proposed controller.
