ABSTRACT:
In a regulated power supply, particularly a pulse-width-modulated supply, the on-off control is located in the feedback path between the supply output terminal and the pulse-width-modulator. Transformer coupled polling pulses sense both the state of the on-off control and the magnitude of the feedback error signal.
