FIELD: electric engineering. ^ SUBSTANCE: transformer 5 is made with additional branches 13, 14 forming two additional windings relatively to edge outputs, while each branch 13 and 14 through resistor 11 and 12 is connected to transistor base 1 and 2, emitter of which is connected to edge output 8 and 9 of same additional winding. Collector-emitter links of transistor 1 and 2 are linked by diodes 3 and 4 in locking direction. Collector of transistor 1 is connected to latch, and collector 2 - to source of MIS transistor. ^ EFFECT: higher reliability, higher efficiency. ^ 1 dwg |
