Abstract
A regulated self-supply power controller for a switched-mode power supply includes an operational voltage supply line having a voltage magnitude that varies between two voltage magnitudes. A controllable power source is intermittently coupled to a capacitor, which is coupled to the operational voltage supply line, on the basis of the variation of the operational voltage supply line voltage magnitude between the two voltage magnitudes.
