Energy efficient regulated power supply system
A regulated power supply circuit includes a transformer having a primary winding and a secondary winding electromagnetically coupled by an iron core. A source of ac operating voltage is coupled to the primary winding of the transformer via an actuable switch means. A load circuit coupled to the secondary winding circuit is adapted to be energized by a voltage developed in the secondary winding circuit. Means are provided for sensing the polarity of each half cycle of said source of ac operating voltage. Memory means are coupled to the transformer for providing information representative of the polarity of each half cycle of the source of operating voltage applied to the primary winding of the transformer. The memory means are operable to maintain the information for a period of time when the switch is actuated to be opened. Means are also provided for sensing a parameter in the secondary winding circuit related to the energy available in the secondary winding circuit. Means couple the memory means, the ac operating voltage sensing means and the parameter sensing means to the actuable switch means.
