PURPOSE:To simplify circuit constitution by taking out a voltage detected for controlling a raster width based on the winding ratio of an inductance circuit disposed in a horizontal output circuit. CONSTITUTION:The one terminal of the inductance 13, 13 is connected to the collector of a horizontal output transistor 2, the other terminal of the inductance 13 is connected to the output end of a series regulator circuit 10 and a clamp capacitor 11 is connected to a connecting terminal taken out from the arbitrary position of the inductance 13. Consequently, the voltage taken out from the winding ratio is clamped by a clamp circuit consisting of the clamp capacitor 11 and a clamp diode 12, rectified in a rectifying circuit consisting of a rectifying diode 8 and a smoothing circuit and applied to the seriese regulator circuit 10. Thereby, the taking out circuit of the detected voltage for controlling the raster width is simplified. |
