Three-phase bridge type thyristor rectifier circuit
The three-phase bridge type thyristor rectifier circuit is as shown in the figure. The difference between this circuit and the three-phase bridge type rectifier circuit is: this circuit uses the unidirectional thyristor to replace the three rectifier diodes of the half bridge arm. You can change the thyristor conduction time of every cycle by changing the conduction angle θ of the three thyristors, and you can get the adjustable DC voltage average value. The three-phase bridge type thyristor rectifier circuit can be used in the speed regulation device of the high power DC motor. Three-phase bridge type thyristor rectifier circuit
