Abstract MAGNETIC DEFLECTION SWEEP AMPLIFIER WITH INTELLIGENT FLYBACK The magnetic deflection sweep amplifier includes a first switch, such as a MOSFET in series with a deflection yoke. The switch is controlled by a second switch, such as a bipolar transistor, and the second switch is able to selectively control the first switch, whereby the yoke current can be reversed, to provide complete flyback, or can be truncated part way through flyback to stop the retrace at an intermediate position. The flyback amplifier also has provision for linear operation without flyback. The present invention accomplishes the foregoing with very few parts and with very little power consumption.
