PURPOSE:To obtain a horizontal deflection circuit in which high speed switching is attained with an excellent characteristic by inserting an impedance element between a low impedance clamp circuit and a base circuit of a horizontal output transistor(TR). CONSTITUTION:A damper current for damper period is suppressed with an impedance element Zx inserted in series with an emitter of a clamp TR Q7 with a low impedance in the horizontal deflection circuit having a clamp circuit B in a base circuit of a horizontal output Tr Q8 with the capacitor coupling system. As a result, it is possible to reduce the damper current flowing between a base and a collector of the TR Q8 from the circuit B and an excess current is quickly eliminated. Thus, the horizontal deflection circuit with high performance is obtained, in which the storage time caused due to the saturation of the Tr Q8 is reduced without losing the substantial switching operation and the high speed switching is attained with less temperature change. |
