DEVICE FOR CONTROL OVER GATING TRANSISTOR Russian patent published in 1994 - IPC

FIELD: electronics. SUBSTANCE: device includes gating transistor, transformer, cut-off transistor, matching resistor, forcing capacitor, charging diodes and winding. Circuit provides for independence of amplitude and duration of current forcing change-over of gating transistor from parameters of current consumed from source of external controlling signal. EFFECT: effective forcing both of cut-off and switching- on of gating transistor within wider range of change of pulse ratio of controlling signal. 5 cl, 3 dwg
