Thyristor module under reverse anode voltage, no matter which kind of voltage, gate under thyristor
module in the off state.
Thyristor module forward under the anode voltage, only in the case of gate under forward voltage thyristor module to conduction.
Thyristor module in conduction case, as long as there is a certain positive anode voltage, however, the gate voltage thyristor module to keep 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 conduction is anode forward voltage, under the condition of thyristor module in the blocking state, 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 module off current through the thyristor is reduced 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.
Zhejiang production of various kinds of specifications models of thyristor rectifier module, thyristor module, solid state relay module, the diode module, rectifier bridge module, such as supporting the radiator products, sincerely look forward to the cooperation with various companies and procurement staff, to provide affordable, quality and reliable electronic components.
