ABSTRACT:
A magnetic deflection amplifier implemented using a linear amplifier connected to a first side of a deflection coil and a three pole switch connected to a second side of the deflection coil. The three pole switch connects the coil to ground during the active scan and connects the coil to a positive or negative high voltage rail depending of the polarity of the retrace current resulting in fast retrace time and reduced voltage requirements on the linear amplifier.
