Abstract
A current-programmed single ended primary inductance converter (SEPIC) topology DC/DC power converter is studied near the threshold of discontinuous operation. Changes in circuit characteristics such as inner loop transfer function as the converter enters the discontinuous region are calculated using average methods, and are compared to measurements. It is demonstrated that the discontinuous SEPIC can exhibit inner loop stability (that is, even with no feedback of the output voltage)
