ABSTRACT:
A horizontal deflection system is operable either from rectified and filtered alternating current line voltage or from a substantially lower voltage direct current voltage source. The need for a step-down transformer in the receiver power supply is eliminated by utilizing the horizontal output transformer to drop the rectified and filtered alternating current voltage when the receiver is operated in the alternating current line mode. The horizontal output transformer is utilized as a step-up inverter when the receiver is operated from the low voltage direct current source to produce a direct current voltage at a point on the horizontal output transformer substantially equal to the rectified and filtered alternating current line voltage.
