| Abstract: | The traditional thyristor trigger circuit is complex, and element is with dispersion, leading to the shift of the trigger. To solve these problems, we designed the digital thyristor trigger circuit, which is based on mierocontroller. The paper in- troduces the system composition, principle of circuit, and carries on simulation and experiment of the circuit. Experimental results show that the circuit can provide the thyristor with trigger pulse accurately according to the digital quantity given. To the trigger angle, the control is in the range of 0-180° ,and the output voltage error is 1.12%. |
