First hydrogen thyratron Q1 and the 3rd silicon stack D3 powers to tested thyristor controlled series compensation, and the second hydrogen thyratron Q2 opens as copped wave simultaneously
Closing, the instantaneous electric charge made on high-voltage pulse capacitor C1 passes through the first inductance L1 oscillating discharge, and voltage transforms to from positive polarity
Negative polarity, now the current oscillation zero passage in the second hydrogen thyratron Q2, and bear backward voltage and make the second hydrogen thyratron Q2
Turning off voluntarily, the first hydrogen thyratron Q1 simultaneously turns off；Negative voltage on high-voltage pulse capacitor C1 makes the second silicon stack D2 lead
Logical, make energy, by the vibration of the second inductance L2 and high-voltage pulse capacitor C1, instantaneous negative voltage be fed back to high-voltage pulse
On the positive pole of capacitor C1, thus form out an energy pulse；
3), step 2 is repeated) form the other three pulse by the first hydrogen thyratron Q1 and the 3rd silicon stack D3 to tested IGCT
Valve group is powered；While forming the other three pulse, the quick charge loop boosted by pulse booster transformer MT, give height
Pressure impulse capacitor C1 provides and supplements energy.
The auxiliary of extra-high voltage converter valve operating test the most according to claim 6 auxiliary energy taking device takes energy method, its
Being characterised by, when producing a pulse, the ON time of the first hydrogen thyratron Q1 and the second hydrogen thyratron Q2 is 1ms, high pressure
The energy payback time of impulse capacitor C1 is 0.66ms.
The auxiliary of extra-high voltage converter valve operating test the most according to claim 6 auxiliary energy taking device takes energy method, its
Being characterised by, the total time producing four pulses is 6.67ms.
