Regulation of DC-TO-DC Power Converters: A Differential Flatness Approach

Abstract Differential Flatness of average models of Pulse-Width- Modulation (PWM) regulated dc-to-dc power converters is demonstrated and exploited for the design of linearizing feedback duty ratio synthesizers achieving local stabilization tasks in converters of the “boost”, “buck-boost” aud “boost-boost” types. The performance and robustness of the proposed feedback regulators are illustrated by computer simulations that include external perturbation inputs.
