Abstract
A non-switched, DC coupled vertical deflection circuit includes a source of a first DC supply voltage that is coupled to a first end terminal of a vertical deflection winding. An amplifier is energized by a second DC supply voltage having twice the magnitude of the first DC supply voltage and the same polarity. An output voltage of the amplifier having the same polarity of each of the first and second DC supply voltages is developed at a second end terminal of the deflection winding. The amplifier produces a deflection current at opposite polarities, during corresponding portions of a vertical trace interval.
