METHOD OF AND DEVICE FOR CONTROLLING MAGNETIC TRANSISTOR SWITCH Russian patent published in 1994 - IPC

FIELD: automatic control and pulse technique. SUBSTANCE: switching current is additionally generated and its energy is transmitted for generating output voltage depending on control voltage level corresponding to logical one preventing switching current energy transfer to switch output and shaping voltage corresponding to logical one across load; at control voltage level corresponding to logical zero switching current energy is transformed and voltage corresponding to logical zero is built up across load. Device for implementing this method has in addition one switching current generator 7 whose second winding is connected accordantly to third winding which is connected to input 1 of output voltage shaper 8; switching current generator 7 is built around capacitor 10 and two resistors 11,12 the former of them being connected to starting lead of second winding and to one lead of second resistor connected through its other lead to first plate of capacitor 10 whose second plate is connected to finishing lead of second winding and in parallel with DC voltage source. Common point of resistors is connected to output of AC voltage source. EFFECT: improved reliability of control. 7 cl, 3 dwg
