Abstract :
The introduction of compensating networks in sliding-mode controlled dc-to-dc switching converters improves the converter start-up behaviour and reduces steady-state errors in the circuit output response. The ideal equivalence among sliding regimes and PWM control responses in nonlinear dynamical systems is used to model the converter dynamics around the equilibrium point. A sliding-mode controlled boost regulator illustrates the application of the method
