In fact the thyristor can be used from milliwatts to megawatts although it is predominantly used at the higher power levels where the transistor cannot compete. Although thyristors were first developed in 1957 they were not accepted immediately for application. At first their power handling ability was not great and they had unstable characteristics in the sense that parameters changed easily with time, temperature and use and varied widely from sample to sample. This has now changed to the extent that the stability is good, thyristors with uniform characteristics are high and power levels are in the megawatt range.

23(b). The corresponding element waveforms are shown in Fig. 23(c). The waveforms describe the action of turn-off. That is, when the capacitor has charged up the resonant circuit tries to make the current reverse so that the thyristor turns off. The conduction period is fixed by the values of Land C. 24 illustrates how the instant of turn-off can be controlled by an auxiliary thyristor TH2 together with the resonating LC circuit. Thyristor TH2 must be fired first to charge C. Thyristor TH2 turns off when the current falls +~------~--~~ Fig.

C. circuit, the anode current can only be reduced by opening the line switch, increasing the load impedance or shunting part of the load current through a circuit parallel to the thyristor, that is, short-circuiting the device. (bj Reverse bias turn-off A reverse anode to cathode voltage (the cathode is positive with respect to the anode) will tend to interrupt the anode current. c. circuit so that a thyristor in the line would be reverse biased every negative cycle and would turn off. c. line commutation.
