The traditional thyristor trigger multi-purpose analog circuit to achieve, as the core of the microcontroller thyristor digital trigger with simple and reliable system hardware, high precision, high intelligence, easy to centralize control, easy fault diagnosis, etc., is the development of thyristor control circuit. The general thyristor digital trigger algorithm there is a long response time, the trigger angle can not be a substantial change and poor reliability and other deficiencies. This paper presents a new thyristor digital flip-flop algorithm. The algorithm overcomes the above shortcomings of the traditional algorithms, and the calculation is simple, fast response, good adaptability, strong anti-interference, occupy less system resources, and in practice received very good results
