5SHY3545L0009 3BHB013085R0001 IGCT integrated gate commutated thyristors are formed by integrating GTO chips with anti parallel diodes and gate driver circuits, and then connecting them to the gate driver in a low inductance manner on the periphery. That is to say, the Gate Integrated GTO (Gate Integrated GTO)
Turn Off)。
IGCT is connected to SCR – pulse in the rectification process. SCR is the abbreviation for Silicon Controlled Rectifier and the abbreviation for silicon controlled rectifier. There are several types of thyristors, including unidirectional, bidirectional, switchable, and optically controlled. It has the advantages of small size, light weight, high efficiency, long service life, and easy control, and is widely used in various automatic control and high-power electrical energy conversion scenarios such as controllable rectification and voltage regulation, inverter, and contactless switch.
Unidirectional thyristor is a controllable rectifier electronic component that can switch from off to on under the action of external control signals. However, once it is turned on, external signals cannot turn it off, and it can only be turned off by removing the load or reducing the voltage at both ends. Unidirectional thyristor is a four layer three terminal semiconductor device composed of three PN junctions PNPN. Compared with diodes with one PN junction, the forward conduction of a single thyristor is controlled by the gate current; Compared with a transistor with two PN junctions, the difference is that the thyristor does not amplify the control electrode current. Bidirectional thyristors have the characteristic of alternately conducting and turning off in two directions. A bidirectional thyristor is essentially two anti parallel unidirectional thyristors, which are semiconductor devices composed of four PN structures formed by NPNPN five layer semiconductors and have three electrodes. Due to the symmetrical structure of the main electrode (both leading out from the N layer), its electrodes are not called the anode and cathode respectively like unidirectional thyristors. Instead, the electrode closest to the control electrode is called the first electrode A1 and the other is called the second electrode A2. The main disadvantage of bidirectional thyristors is their low ability to withstand voltage rise rates. This is because when the bidirectional thyristor completes conduction in one direction, the carriers in each layer of the silicon wafer have not yet returned to the cutoff state, and corresponding protective measures must be taken. Bidirectional thyristor components are mainly used in AC control circuits, such as temperature control, lighting control, explosion-proof AC switches, and DC motor speed regulation and commutation circuits. The thyristor remains in the on state above the current, with high turn off current, difficult control, and slow turn off speed. In the inverter stage, SCR has excellent performance in LCI (load commutation inverter), which can achieve ultra-high power, high voltage, and high current. Both diode (controllable rectification device) and SCR (semi controllable) rectification do not require PWM to meet the operation of two quadrant frequency converters, while PWM requires IGBT (fully controlled) and other devices.

ABB 5SHY3545L0016 Controllable silicon thyristor module
ABB 5SHY3545L0016 Product details of thyristor module:
ABB Focusing on the fields of power and automation technology. Regarding the ABB 5SHY3545L0016 you mentioned, it is a thyristor (SCR) module produced by ABB, used for applications such as power control, converters, and energy regulation.
A thyristor is a semiconductor device used for power control and regulation. It can control the on/off of high currents in circuits and is commonly used in applications such as inverters, speed control devices, and electric furnace control. The following are possible application areas:
Power converter: The thyristor module is used in power system converters to convert alternating current into direct current or vice versa, thereby achieving control and distribution of electrical energy.
Motor speed regulation: thyristor can be used for speed regulation devices, such as speed control of AC motors, to meet the needs of different working conditions.
Power regulation: In power transmission and distribution systems, thyristor modules can be used to control the transmission, distribution, and regulation of electrical energy.
Industrial heating: In industrial production, thyristors can be used to control equipment such as electric furnaces and resistance heating.
Lighting control: The thyristor module can also be applied to lighting systems to achieve brightness control of lighting.
Energy feedback: In energy feedback systems, thyristors can be used to control the storage and release of energy.
The company has a leading advantage in discontinuing control system components.
