FIELD: pulse equipment for use in commutation devices.
SUBSTANCE: transformer 5 has additional winding, edge contacts of which are connected to bases of transistors 1 and 2, emitters of which are connected and through resistor 9 are connected to middle point of additional winding, and collector-emitter transfers are linked by diodes 3 and 4 in locking direction. Collector T 1 is connected to start of secondary winding TP 5, end of which is connected to source of MIS-transistor 10, gate of which is connected to collector T 2.
EFFECT: higher reliability, higher efficiency, higher resistance to interference.
