Abstract

A current-programmed controlled push-pull converter intended for space applications is analyzed. The canonical small-signal model of the current-programmed current-fed push-pull power stage is formulated to facilitate the system design. An optimum slope of the stabilizing ramp which eliminates the inherent instability in this system is proposed. In the closed-loop controlled converter, an appropriate compensator is designed so that overall system is stable and meets the specifications. Computer simulation using the software packages MATLAB and IsSpice, and experimental results are used to verify the theoretical work. In addition, the practical considerations in a prototype design are discussed
