Abstract

This paper presents on the continuous conduction mode (CCM) of operations of a flyback SMPS and stability analysis based on inclusive study and operating dogma. The modeling of the SMPS enlightens the stability with the power components and feedback loop. It is worked out by unbreakable poles and zeros of the transfer function of the SMPS, since the coupled inductor in the CCM is palpably a current source and the dominating pole is just the broken by the output capacitor and load resistor. This prediction predicts the upper limit of phase shift that is about 90 degrees of the closed loop stable operation.
