FIELD: pulse work. ^ SUBSTANCE: power key for DTM-transistor containing identical conductivity transistors with collector emitter junctions in bridge with diodes in locking direction, resistor. Collector of one transistor is connected to DTM-transistor shutter, and collector of other transistor is connected to input of secondary transformer winding output of which is directly connected to DTM-transistor source. Transformer has additional secondary winding with midpoint. Transistor bases are connected directly, and additional secondary winding is connected between transistor emitters. Output of additional secondary winding is connected to emitter of that transistor collector of which is connected to DTM-transistor shutter, and midpoint of additional secondary transformer winding is connected through resistor to transistor bases. ^ EFFECT: higher reliability and downsizing. ^ 1 dwg |
