ABSTRACT:
A vertical deflection circuit for television receivers or the like which has an output stage of single-ended push-pull amplifier configuration is provided with a power supply circuit which includes a rectifying circuit connected between a D.C. voltage source and the output stage for rectifying an external A.C. voltage fed thereto to produce an additional D.C. voltage. The power supply circuit supplies a first D.C. voltage from the D.C. voltage source to the output stage during the first half of a trace or scanning period and supplies a second D.C. voltage, obtained by adding the additional D.C. voltage to the D.C. voltage from the D.C. voltage source, to the output stage during the second half of the trace or scanning period and during the retrace period.
