摘要：A vertical deflection current generator includes an operational amplifier (31)responsive to an input sawtooth signal (VS) at a vertical rate. A first end terminal of a deflection winding (LV) is coupled to an output terminal (31a) of the amplifier (31). A贝斯几根弦
cond end terminal (60) of the deflection winding (LV) is coupled in ries with a parallel
arrangement of a switch (32) and a capacitor (CR). The switch (32) is conductive during vertical trace. During vertical retrace, the switch (32) is nonconductive, which caus a vertical retrace voltage (VCR) to develop in a flyback manner in the retrace capacitor (CR). The retrace voltage (VCR) in the retrace capacitor (CR) and a retrace voltage (Vv) at the output terminal (31a) of the amplifier (31) are opposite in pha and speed up the reversal of deflection current in the deflection winding (LV).
