Abstract

The optocouplers replace the synchronization transformers to simplify the synchronizing circuits in AC/DC convertors and in AC power controllers. Simple circuits are described for synchronization of 1-amp;phi; and 3-amp;phi; control circuits. The methods explained are simple and economical in size and cost. The experimental waveforms obtained are given. The circuits can be used in synchronizing the triggering signals in variable frequency circuits like induction motor drives
