Abstract
1528625 Transistor amplifying and deflection current generating circuits UNITED TECHNOLOGIES CORP. 8 Oct 1975 [9 Oct 1974] 41222/75 Heading H3T In a system for supplying current to a load 14 (e.g. the deflection coils of a cathode-ray tube), part of the current is supplied by means of a linear amplifier 12 in response to desired current signals Vin and includes switching means responsive to the desired current signals Vin of both polarities in excess of a given magnitude for connecting a constant current source in a corresponding polarity to said current load 14 and, responsive to absence of input signals in excess of said given magnitude for disconnecting said current source from said current load 14. As described, a sawtooth voltage swinging from a negative value to a positive value is applied at Vin to a linear amplifier 12 capable of producing an output current of
