KOPPLINGSKRETS FOR ALSTRING AV EN STYRLIKSPENNING SOM ER BEROENDE AV EN VEXELSPENNING

摘要

In a circuit for the generation of a direct control voltage dependent upon an alternating voltage the changing of the control voltage is delayed after a rapid decrease in the alternating voltage amplitude. This delay time is controllable in dependence upon the time difference between an increase and a rapid decrease of the alternating voltage amplitude.
