摘要：First and second capacitors are charged from a DC source of unregulated input voltage through the primary winding of a flyback transformer of a horizontal deflection circuit. The average voltage across the first capacitor is established as the voltage difference between the input voltage and the average voltage across the second capacitor. The first capacitor functions as a trace capacitor for a horizontal deflection winding. A switch applies a trace voltage to the horizontal deflection winding to generate a trace deflection current. The switch also applies the voltages developed across the second capacitor and across a flyback transformer secondary winding to a regulator inductance to control the flow of current in the second capacitor. The current flowing through the inductance is varied in order to control the voltage across the second capacitor for regulating a selected deflection circuit quantity.
