| Abstract: | The application of sliding mode variable structure control was studied for Buck converter and a novel PWM-based sliding mode controller was designed to resolve the problem that the performance of Buck converter controlled by sliding mode controller was impacted by the switching frequency of components. An experimental prototype was developed, and the experiment results indicate that Buck converter controlled by the proposed method has high accuracy, speedy dynamic response and strong robustness against the ... |
