彩电行输出电路的作用就是通过开关信号的激励,在行偏转线圈中产生行锯齿波电流,使显像管电子束沿荧光屏作水平运动。同时,在行输出级接入行逆程变压器,用以产生其他单元电路所需的各种脉冲或直流电压。与一般放大电路不同,要在行偏转线圈中产生合符要求的锯齿波电流,不能输入锯齿波信号,而 Color TV line output circuit is the role of the switch signal through the excitation in the line deflection coil to generate a line sawtooth wave current, so that the tube electron beam along the screen for horizontal movement. At the same time, in the row output stage access line reverse transformers, used to generate the various other units required for a variety of pulse or DC voltage. Different from the general amplifier circuit, it is necessary to generate a sawtooth wave current that meets the requirements in the line deflection coil, and can not input the sawtooth signal, and
