ABB 5SHY4045L0006 3BHB030310R0001 IGCT module


IGCT Integrated Gate Commutated Thyristors (IGCT) is a new type of power semiconductor switching device (integrated gate commutated thyristor=gate commutated thyristor+gate unit) developed by medium voltage inverters and used in giant power electronics packaged devices. It was proposed by ABB in 1997. IGCT enables the converter to operate at
Significant progress has been made in power, reliability, switching speed, efficiency, cost, weight, and volume, bringing a new leap forward to complete power electronic devices. IGCT integrates a GTO chip with an anti parallel diode and gate driver circuit, and then connects it with its gate driver in a low inductance manner on the periphery. IGCT combines the advantages of the transistor’s stable turn-off capability and the low on-state loss of the thyristor, giving play to the performance of the thyristor during the turn-on phase, and presenting the characteristics of the transistor during the turn-off phase. IGCT has the characteristics of high current, high blocking voltage, high switching frequency, high reliability, compact structure, and low conduction loss, as well as low manufacturing cost and high yield. It has been widely used in power system power grid devices (100MVA) and medium power industrial drive devices (5MW). IGCT has been successfully applied in the field of medium voltage inverters for 11 years (until 2009). Due to its high-speed switching ability, IGCT does not require buffer circuits, As a result, fewer power components are required and operational reliability is greatly improved.
IGCT integrates the high-speed switching characteristics of IGBT (insulated gate bipolar transistor) and the high blocking voltage and low conduction loss characteristics of GTO (gate off thyristor). Generally, trigger signals are transmitted to IGCT units through optical fibers. In the phase module of the rimmed rectifier unit of the ACS6000, each phase module is composed of an IGCT, a diode, and a clamp capacitor, and is powered by an independent gate power supply unit GUSP.

Using PLC to control the system is very convenient. This is because: first, the establishment of PLC control logic is a program, replacing hardware wiring with a program. Programming is much more convenient than wiring, and changing the program is certainly much more convenient than changing the wiring!
Secondly, the hardware of PLC is highly integrated and has been integrated into various miniaturized modules. Moreover, these modules are complementary and have been serialized and standardized. The modules required for various control systems are mostly supplied by PLC manufacturers and can be purchased on the market. Therefore, the hardware system configuration and construction are also very convenient.
Because of this, the word “can” exists only with programmable controllers. For software, its programs are programmable and not difficult to compile. For hardware, its configuration is variable, and it is also easy to change.
Specifically, PLC has five advantages:
(1) Convenient configuration: To meet the needs of the control system, determine which PLC to use, which type, what modules to use, and how many modules to use. After determining, order and purchase from the market.
(2) Convenient installation: PLC hardware installation is simple, and assembly is easy. External wiring is provided with a connector, which is simple to connect. When replacing a module after one connection, it is sufficient to install the connector onto the new module, without any further wiring. Do not connect any internal wires, just make some necessary DIP switch settings or software settings, and prepare a user program to work.
(3) Convenient programming: Although there are no actual relays, time relays, and counters inside the PLC, these devices actually exist through programs (software) and system memory. The number is unimaginable for relay control systems. Even for small PLCs, the number of internal relays can be counted in thousands, while the number of time relays and counts can also be counted in hundreds. Moreover, the contacts of these relays can be used * * times. There are so many internal logic devices in PLC that users no longer feel any restrictions when using them. All that is considered is entry and exit points. It doesn’t matter how much this internal entry and exit point is used. The control points of a large PLC can reach more than 10000 points. How can there be such a large practical system? If it is not enough, it can also be controlled online without any restrictions. The command system of PLC is also very rich, which can easily achieve various switching values and analog control. The PLC also has a memory area for storing data, which can store all the information to be saved during the control process In short, due to the powerful functions of PLC, the restriction on its role in the control system is no longer the PLC itself, but people’s imagination, or other hardware facilities supporting it.
