Abstract
This paper presents the digital implementation of a recently developed boundary control method with second-order switching surface for inverters. The control principle is based on estimating the state trajectory movement after a switching action, resulting in a high state trajectory velocity along the switching surface. This phenomenon accelerates the trajectory moving towards the target operating point. The mathematical derivation and generation of the gate signal and feedback signal will be given. A 320 W prototype has been built and tested. The large-signal dynamic responses of the inverter will be given.Keywords
