Abstract
A feedback voltage regulator for a television deflection apparatus having a deflection switching arrangement driving a deflection winding and supplied with power from a source of potential through a first inductor includes a second inductor coupled in series with the first. The second inductor conducts a substantially direct current towards the source of potential. An SCR is coupled in parallel with the second inductor and its conduction is duration modulated in response to the regulated voltage. The duration modulation controls the time during which the direct current is withdrawn from the deflection switching arrangement and first inductor and thereby maintains the regulated voltage substantially constant.
