Abstract

A new nonlinear control strategy is proposed to control switching-mode power converters. The controller can correct switching errors thoroughly with linear resetting technique reversely. There is no steady-state error when the power source voltage is perturbed. The converter can operate steadily under the condition of discontinuous conduction or critical condition with automatic limited integration output. The double feed-forward compensation provides optimizing transient response for load disturbance. The proposed method can get excellent performance in power source perturbation rejection, following the reference and load disturbance rejection. The proposed method is very general and applicable to most types of resonant based or soft-switched PWM converters.
