Thyristor module working conditions: 1.
Thyristor module under reverse anode voltage, no matter which kind of voltage, gate under thyristor
is in the off state.
Thyristor module forward under the anode voltage, only in the case of gate under forward voltage thyristor conduction.
Thyristor module in conduction case, as long as there is a certain positive anode voltage, however, the gate voltage thyristor conduction, namely the thyristor turn-on, after the gate.
Thyristor module in conduction case, when the main circuit of voltage (
Reduce to close to zero, thyristor turn-off.
Conduction conditions please see point 2 thyristor module conduction is anode forward voltage, under the condition of in the blocking state of thyristor, only in the gate and positive trigger voltage, can make its conduction.
Gate puts forward the minimum width of trigger pulse, should be able to make the anode current reaches the minimum needed to maintain state anode current, namely the qing lived more than current IL.
After the conduction of thyristor control pressure drop is very small.
Make the conduction of the conditions of the thyristor turn-off current through the thyristor module is to decrease to a small number, is to maintain current IH.
Its method has two: 1, reduce the positive anode voltage to a value, or reverse anode voltage.
2, increase the resistance of load circuit.
Thyristor module will only a little more than a rival, it is much to consider for the customer.
If interested in our thyristor module or there is doubt, welcome your consultation.
