Asynchronous digital linear–nonlinear control

Abstract

At present, digital control solutions are becoming more attractive than analogue implementations in some power converter applications owing to easy design of complex control strategies and control reconfigurability. The digital implementation of an asynchronous linear–nonlinear (LnL) compensator to improve the dynamic response of interleaved buck converters is proposed and validated. It is important to highlight that the same digital LnL compensator is able to keep the dynamic response even with very important variations of the control and the power stage parameters.
