Description

technical field [0001] The invention relates to the technical field of fault detection of electronic components, in particular to a thyristor detector and a thyristor detection method of the detector. Background technique [0002] Thyristors are widely used in various electronic equipment and electronic products, and are mostly used as controllable rectification, inverter, frequency conversion, voltage regulation, non-contact switches, etc. Once the thyristor is damaged, it will directly cause the equipment to fail to work. The maintenance and replacement of thyristors Most of them are carried out by on-site maintenance personnel. [0003] To detect whether the thyristor is good or bad, the field generally uses a multimeter to measure the resistance method, that is, after disconnecting the wiring of the thyristor, the measurement: the anode and the cathode are disconnected, the gate (control electrode) and the cathode are connected in one direction, and there are dozens to s...
