A deflection driver in a video apparatus.

摘要

A driver stage (100) for a horizontal deflection output transistor (Q2) includes a transformer (T1) having a first winding (W1) coupled to an input signal (Ic1) at a horizontal deflection frequency, a second winding (W2) coupled across a base-emitter junction of the output transistor (Q2) and a third winding (W3) coupled to the emitter of and in series with the output transistor (Q2). The third winding (W3) couples the emitter current (Ic2) to the base of the output transistor (Q2) for supplying a substantial portion of the base current (Ib2) during the second half of trace. <IMAGE>
