Abstract
A regulated power supply for a television receiver includes a transformer having a primary winding coupled to a source of unregulated voltage. A transistor switch controls the interval during which the unregulated voltage causes current to flow in the primary winding. By transformer action, power is transferred to secondary windings which are coupled to receiver load circuits. The secondary winding voltages are regulated by control of the primary winding conduction interval. A supplemental winding is layer wound over the primary winding to transfer additional power to the load circuits. The primary winding may be electrically isolated from the secondary windings and from the supplemental winding.
