Abstract

PURPOSE:To ensure maintenance of a constant size of the picture with use of a simple circuit constitution even to the fluctuation of the power voltage as well as to the disturbance applied to the horizontal output part by adding a circuit which controls the output voltage of the power circuit in order to secure a constant current for the deflecting coil. CONSTITUTION:Switching regulator 3 is provided to change input DC unsteady voltage Ei sent from the power source into the stabilized output DC voltage Eo, along with Schmitt trigger circuit 2. Voltage Eo is then applied to horizontal deflecting circuit 1 which supplies the current to deflecting coil L1. Horizontal deflecting current detecting resistance R1 which detects the deflecting current of coil L1 is installed to circuit 1 in series to coil L1, and the voltage detected by R1 is applied to the input terminal of circuit 2. Then the pulse of the value more than the fixed level is generated at circuit 2, and the pulse duration control is given to switching transsistor TR5 of regulator 3. Thus, the fluctuation caused by the disturbance applied to circuit 1 can be prevented effectively.
