This paper presents the functional description and the design of a fully digital integrated circuit for thyristor firing control in a 1 μm CMOS technology. The architecture is based on the equidistant firing method, which allows the change of the displacement between two consecutive pulses before the zero crossing of the AC power source that is used as a synchronism signal. The circuit is designed fully digital, thus requiring no adjustments and providing high reliability and low cost. In this paper the performance of the circuit is shown by the simulation results under different operation conditions
