Title: Compensation circuit for colour TV receiver - eliminates effects of picture outline correction on tube HV supply by adding winding in series with transformer primary
Inventor: POLLAK ALFRED
IPC: H04N3/237
Filed: 1979-12-21
Abstract: The circuitry for colour t.v. receivers fitted with a compensation circuit for correcting the tendency for the picture to be wider at the top and bottom than in the middle. The modification to compensation using a 50Hz vertical modulation of the line scan is intended to prevent modulating the tube HV supply. The correcting modulation (13,14) is applied to the control winding (12) of the line scan transducer (11). Its effect is to change the impedance of the transductor continuously over one complete picture thus providing the required correction in the line scan control circuit (1). A winding, typically in two sections (15a,15b) is added to the transductor and connected in series with the HV transformer (3) primary winding (4). Its effect is to counteract the modulation effect on the HV output to the tube (7) by keeping the voltage across the primary winding sensibly constant.
