This so-called "bridge rectifier" consists of 4 thyristors and one AC voltage source. The DC-side inductor is connected in series with the voltage source. This circuit allows current to flow from both the positive and negative half cycles of the source voltage. The current from the source must now always flow through two thyristors. Controlling the firing angle of the thyristors allows for control of the average output voltage, which is not possible with a diode bridge rectifier. Current can only flow from the AC side to the DC side. With a voltage source on the DC side (not available in this animation), a negative load voltage would be possible and power could be delivered from DC to AC (e.g. electrical drive).

• Change the resistance or inductance values of the load. This will influence the conducting period of the thyristor if the current is not continuous.
• Set a different triggering angle by changing the signal 'ref'. If 'ref' crosses the triangular signal 'sig' , the firing pulse triggers the thyristor into the on-state. This will change the average output voltage. It will also phase shift the current and change the power factor accordingly.
• Drag the time slider from left to right. After passing the trigger point, the trigger pulse is animated. After triggering, the thyristor is in the on-state and the load current keeps flowing.
