Abstract
An electromagnetic deflection display system is operative for bi-directional raster and stroke deflection and provides minimum power dissipation in raster mode during a segmented or patch raster display. Energy stored in the deflection yoke during one direction of the raster scan is returned to an energizing power supply during the subsequent return scan in a manner that conserves power while avoiding an over-voltage condition of the associated power supply. A transformer is coupled to receive a portion of the energy stored in the yoke and return it to a designated raster mode power supply. The raster mode return voltage may be determined independently of stroke mode power requirements so as to optimize raster power savings and ampifier raster performance independent of the optimum stroke voltages.
