Description

technical field [0001] The present application relates to the technical field of thyristor detection, in particular to a simple detection board for thyristor. Background technique [0002] In the production and maintenance process of electronic and electrical equipment, the process needs to use the electronic component of the thyristor, and naturally it often encounters the problem of testing the performance of the thyristor (thyristor). In the prior art, the detection of silicon controlled rectifiers usually uses a "transistor characteristic tracer" to detect silicon controlled silicon. However, the "tracegraph" is expensive, bulky, inconvenient to carry, and inconvenient to use, and there is no such equipment in general production and maintenance occasions. [0003] As we all know, thyristors are divided into one-way thyristors and two-way thyristors. One-way thyristors have single-phase conductivity, but they are different from ordinary diodes in that their anode (A) and...

Problems solved by technology

It can be seen that there are many steps in the detection process of silicon controlled rectifiers.

[0004] In the prior art, if there is no "transistor characteristic graph instrument", the inspector can only detect manually. He must connect the silicon controlled rectifier to be detected to both ends of the power supply, use a test meter to detect whether it is conductive, and then Apply a pulse with the power supply, and then check whether it is conductive. After that, it is necessary to reverse the thyristor to be tested and the power supply before testing. The whole process is extremely cumbersome, the detection efficiency is low, and the detection process is prone to errors.
