Single phase bridge type thyristor rectifier circuit
Single phase bridge type thyristor rectifier circuit
The single phase bridge type thyristor rectifier circuit is composed of the single phase bridge type rectifier circuit, the unidirectional thyristor and the load RL, as the figure shows. The single phase AC voltage is bridge-type rectified by this circuit and becomes the full-wave rectifier waveform. Because only when the trigger signal increases, the thyristor will conduct, and the thyristor is cut off when the AC voltage is crossing zero, so we can get the waveform which is as shown in figure (5). From the figure a and b, we can see that when the angle θ is small, the DC voltage average values at both ends of the load resistanceare small; when the angle θ increases, the DC voltage average values of the load resistanceare high.
