Abstract
A power supply regulator in which a control pulse is generated at a position in time which varies in accordance with the voltage or current supplied by the power supply. The control pulse can be fed back across an isolation boundary with a simple device such as a pulse transformer with little or no loss of accuracy. Such a control signal is particularly adaptable to varying the duty cycles of transistor switch drive signals for switched-mode power supplies.
