ABSTRACT:
A high-voltage zero-crossing detector comprising a voltage divider having a rectifier at its output, a stabilitron limiter and a transistorized blocking generator whose transistor base is connected via a capacitor to one of input terminals of the rectifier. Connected in parallel to an output of said rectifier are an energy storage capacitor and a series circuit made up of two capacitors shunted by the stabilitrons of the stabilitron limiter, their common point being connected to the emitter of the blocking generator's transistor which has its collector connected via the winding of a transformer of the blocking generator and a dinistor to the output of the rectifier.
