Littelfuse, Inc., the global leader in circuit protection, today introduced a series of 40A standard high-temperature silicon-controlled rectifier (SCR) thyristors that are ideal for use as switches ...

The circuit in the diagram is a very handy tool for rapidly checking all kinds of thyristor (SCR, triac, …). In case of a triac, all four quadrants are tested, which is done with S3, while in case of ...

The thyristor d.c. drive remains an important speed-controlled industrial drive, especially where the higher maintenance cost associated with the d.c. motor brushes (c.f. induction motor) is tolerable ...
