Abstract
It is possible to achieve more precise power regulation in switched mode power supply systems by performing at least some control-loop processing on the secondary-side of the transformer. In particular, a secondary-side measurement is processed at least partially by a secondary-side controller to obtain a switching indication signal. The switching indication signal is then communicated from the secondary-side controller to a primary-side controller, where it is used to regulate the amount of energy applied to the primary winding. The switching indication signal may be any control signaling instruction that prompts the primary-side controller to regulate and/or modify the power applied to the primary winding. The switching indication signal may be communicated over an isolating signal path, such as a single-ended capacitive coupler, a differential capacitive coupler, an inductive coupler, or an opto-coupler.
