Thyristor module damage, if not same thyristor
module replacement, can choose other types of similar with its performance parameters thyristor module to substitution.
Application circuits are usually leave when the design bigger margin.
When replacement thyristor module, as long as the attention to its nominal peak voltage (
Repetitive peak voltage)
, rated current (
State the average current)
, the gate trigger voltage and gate trigger current, especially peak rated voltage and rated current of these two indicators.
Substitution thyristor module should be consistent with the damage to the switching speed of thyristor module.
For example: in the pulse circuit, the inverter circuit using high-speed thyristor module damage, can only choose the same type of fast thyristor module, rather than using ordinary thyristor module to substitution.
Select alternative thyristor module, no matter what parameters, don't have to have big margin, should as far as possible with the substitution of thyristor module parameters, because too much allowance is not only a kind of waste, and sometimes the side effects, don't trigger or triggering the phenomenon such as insensitive.
In addition, also notice the appearance of two thyristor module should be the same, otherwise it will bring bad installation work.
Zhejiang rectifier co. , LTD. , the production of various kinds of specifications models of thyristor module, MTC thyristor modules, solid state relay module, rectifier bridge module, such as supporting the radiator products, sincerely look forward to the cooperation with various companies and procurement staff, provide affordable, quality and reliable electronic components.
