Implementation Of Natural Switching Surface Control For A Flyback Converter, Ethan Storm Williams

Electrical Engineering Undergraduate Honors Theses

The flyback converter is an extremely common topology used for DC/DC power conversion. Widely used methods to control the flyback converter include voltage mode and current mode controllers. More recently, sliding mode control has been developed for the flyback converter. While these control methods may be considered adequate, the Natural Switching Surface (NSS) sliding mode control method detailed in this thesis presents a more robust controller. NSS control eliminates the effects presented from variations in components and design as well as minimizes the effects from external disturbances. This thesis steps through the complete design and implementation process of a NSS …
