Abstract :
This paper presents interleaved buck converters using a switching rule based on winner-take-all nonlinearity. The switching rule can realize flexible phase control and the system can generate various interesting synchronous phenomena. Using a simple piecewise constant model, we clarify parameters conditions for existence and stability of the phenomena. We also discuss current sharing and ripple reduction for practical applications.
