GENERATOR OF OPERATING VOLTAGE AND HORIZONTAL POLARIZED CURRENT

摘要

This circuit arrangement can be switched to mains and battery operation. In battery operation, the power supply/horizontal deflection stage (N1,H) operates as deflection stage. For battery operation, an additional switched-mode power supply (N2) is used which is controlled by the pulse generator stage and regulating circuit of the power supply/horizontal deflection stage, the drive pulses from the existing pulse generator and regulating stage being connected to the switched- mode power supply (N2) via a delay circuit (22).
