5SHX1445H0002 ABB Driving device IGCT Category: ABB Published: Nov 10, 20225SHX1445H0001 ABB Driving device IGCT thyristor. IGCT has the characteristics of large current, high blocking voltage, high switching frequency, high reliability, compact structure, low conduction loss, low manufacturing cost, high yield, and good application prospects.

Thyristors can be divided into ordinary thyristors (SCR), bidirectional thyristors (TRIAC), reverse thyristors (RCT), gate turn-off thyristors (GTO), BTG thyristors, temperature controlled thyristors (TT abroad, TTS at home) and optically controlled thyristors (LTT) according to their turn-off, turn-on and control modes.

According to its pins and polarity, thyristors can be divided into two electrode thyristors, three electrode thyristors and four electrode thyristors.

According to its packaging form, thyristors can be divided into three types: metal-encapsulated thyristors, plastic-sealed thyristors and ceramic encapsulated thyristors. Among them, metal encapsulated thyristors can be divided into bolt shape, plate shape, round shell shape and so on. Plastic-sealed thyristors are divided into two types: with and without heat sink.

According to current capacity, thyristors can be divided into three types: high-power thyristors, medium-power thyristors and low-power thyristors. Generally, high-power thyristors are mostly ceramic packages, while medium and low-power thyristors are mostly plastic or metal packages.

Thyristors can be divided into ordinary thyristors and fast thyristors according to their closing speed, fast thyristors include all thyristors designed for fast applications, there are conventional fast thyristors and high frequency thyristors working at higher frequencies, can be applied to 400HZ and 10KHZ above the chopping or inverter circuit. (Note: High frequency cannot be equated with fast thyristor)
