Abstract
An integrated off-line AC to DC power supply is disclosed. Alternating current (AC) line voltage is supplied (optionally) to an AC voltage to current converter and then (optionally) to a voltage limiter and rectifier which utilizes both MOS devices and inherent junction devices as either a full or half wave rectifier. The rectifier output is supplied to a series-pass junciton device voltage regulator or a regulator which has pre-set voltage output or user-selectable voltage output.
