Transistor controlled rectifier circuit a

Without affecting the accuracy of engineering calculations, when analyzing the rectifier circuit below, both the thyristor and the rectifier diode are regarded as ideal
components , that is, the forward voltage drop during turn-on and the leakage current during turn-off are ignored. ·And the turn-on and turn-off are instantaneous.
    The thyristor controlled rectifier circuit is shown in Figure 12-8a-d. Their working principles are similar to ordinary diode non-controllable rectification circuits
. The difference is that the thyristor must have a forward voltage between the anode and the cathode, and a certain trigger pulse between the gate and the cathode. signal
to conduct the work. Each thyristor requires a trigger circuit. The load is resistive and inductive.
