SU457174A1 - Pulse shaping device - Google Patents

Description

magnetic flux in the core of the throttles; the magnetic flux in its core increases until the core goes into saturation. After filling the core of the throttle 6, the process of discharging capacitor 7 to capacitor 16 begins. The transfer of the generated impulse when discharging capacitor 7 is carried out through transformer 1, capacitor 16, pulse shaping unit 3 to the primary winding 17 of the output pulse transformer 18, the secondary winding 19 of which is connected to the communication channel. The discharge of capacitor 7 is unidirectional, since the inductance of charge throttles 8 is significantly greater than the inductance of the main winding 5 of the switching throttle 6 in a saturated state, therefore the bypass effect of the inductance of charge throttle 8 is negligible, and the discharge current of the capacitor 7 flows through the main winding 5 Drossel 6, but the primary winding 4 of the transformer 1, through diodes 9-12 rectifier and capacitor 13. The presence of a full-wave rectifier on diodes 9-12, a smoothing capacitor 13 allows biasing it choke 6 when changing the polarity of the supply voltage.
