A Retrace Driven Television Horizontal Deflection Circuit

A general trend for the use of silicon controlled rectifiers (SCR) in television line-scanning generators leads, in principle, to new circuit configurations /1/, in which the deflection coils are driven during the retrace via a switching element. Instead of the SCR, transistors may be used as well, In the present paper, optimum working conditions of this circuit diagram are determined and equations derived enabling a simple engineering design of this generator. The wiring diagram mentioned in the paper has a high-voltage circuit part designed in an unique way.
