Abstract

Thyristors have a very important role in power electronics. These devices can control MW power using simple electronic signals of milliwatt power. In this article a simplified schematic approach using 555 timer and 741 operational amplifier is adopted to develop practical three phase firing circuit for any application of thyristors like controlled rectifiers investors and power regulators.
