Abstract
An AC to DC power supply is provided based on feedback control of an analog current blocking (ACB) device. The ACB element receives rectified high voltage AC. The output of the ACB element is provided to an integrating circuit that provides an output DC voltage. The output DC voltage depends on the average current passed by the ACB element. The average current passed by the ACB element depends on the current limit of the ACB element, which is under feedback control.
