Abstract

The large signal stability and transient response of a buck-boost programmable switching regulator employing adaptive gain current injected control (CIC) are investigated. The stability of the regulator is analysed studying the equilibrium points of the system. The type of the equilibrium points is determined by the linearized about the equilibrium point state space averaged model of the regulator. The linearized model is used also for proper initial selection of the feedback coefficients. The transient responses of the buck-boost programmable switching regulator employing normal and adaptive gain current injected controls are compared. It is found that the adaptive gain CIC improves the dynamics of the regulator working at different operating conditions. The simulation runs are verified experimentally
