Abstract

1,028,954. Semi-conductor pulse circuits. DANFOSS A/S Jan. 21, 1965 [Jan. 21, 1964], No. 2736/65. Heading H3T. [Also in Division G4] An analogue voltage U A is applied to a solidstate threshold device 4 which is in turn connected to an integrating capacitor 5 and a differentiating capacitor 7. When the difference between U A and U C exceeds the threshold voltage, device 4 switches to a low resistance state, the direction of conduction through device 4 depending on the polarity of the difference between U A and U C . As U A rises by one increment, device 4 conducts and capacitor 5 is charged until the current through device 4 drops to a predetermined low level. A positive pulse is derived from capacitor 7 and passes through diode 9 for each positive increment of U A . A negative pulse is derived from capacitor 7 and passes through diode 12 for each negative increment of U A .
