NOTES: A. Resistor R1 is adjusted for the specified value
B. Resistor R2 value is 30/IH, where IH is the
holding current value of thyristor TH1.
C. Thyristor TH1 is the same device type as the
D. Pulse Generators, G1 and G2, are
synchronised to produce an on-state anode
current waveform with the following
tP = 50 μs to 300 μs
duty cycle = 1%
E. Pulse Generators, G1 and G2, have output
pulse amplitude, VG, of ³ 20 V and duration of
10 μs to 20 μs.
