Abstract : The recent introduction of high current-capacity thyristors has advanced the status of solid-state power supplies. ON-OFF switching of an entire rectifier, bridge, rather than individual thyristors, provides a simple and economical method of control and regulation. This control philosophy causes the system to limit cycle. A describing function is developed to model the power-supply input transformer and rectifier bridge. The describing function is then used to predict the frequency and amplitude of the limit cycle. A digital computer program is used to construct the describing function curves, and to simulate the dynamic response of the system. Limit cycle predictions are compared with the simulated response to verify the describing function validity. (Author)
