Fundamental Characteristics of Thyristors (PDF 74p)

EBook Description: The Thyristor family of semiconductors consists of several very useful devices. The most widely used of this family are silicon controlled rectifiers(SCRs), Triacs, SIDACs, and DIACs.

Notes on Thyristor application circuits.

RC Snubber Networks for Thyristor Power Control and Transient Suppression (PDF 25p)

RC networks are used to control voltage transients that could falsely turn-on a thyristor. These networks are called snubbers.

THREE PHASE CONTROLLED RECTIFIERS (PDF 62p)

Three-phase controlled rectifiers have a wide range of applications, from small rectifiers to large
High Voltage Direct Current (HVDC) transmission systems. They are used for electro-chemical
process, many kinds of motor drives, traction equipment, controlled power supplies, and many
other applications.

Thyristor Theory and Design Considerations

Thyristors can take many forms, but they have certain things in common. All of them are solid state switches which act as open circuits capable of withstanding the rated voltage until triggered.

THYRISTORS Notes

The term Thyristor defines a broad range of solid-state components which are used as electronically controlled switches. Each of these devices can switch between a conducting (on) state and a non-conducting (off) state to effectively pass or block electrical current. Some Thyristors are capable of switching currents flowing in one direction while others can switch currents flowing in either direction.
