Abstract

This chapter provides tools to control switching electronic power converters. It starts by explaining techniques to obtain linear state-space converter models, illustrating them through examples. Linear models are then used to design linear feedback controllers for converter operating in the continuous or discontinuous mode.

Nonlinear state-space models and sliding-mode controllers are next used to define exactly the variables to be measured while providing the control and switching laws aiming for robust modulator and controller design.
