5SHY3545L0020 IGCT module
The basic principle for selecting the 5SHY3545L0020 model is to choose a reliable, easy to maintain and use, and high-performance model while meeting the functional requirements. The usual practice is to use an integral structure PLC for 5SHY3545L0020 in situations where the process is relatively fixed and the environmental conditions are good; In other cases, a modular structure PLC is selected; For engineering projects with switch control as the main control and 5SHY3545L0020 with a small amount of analog control, the control speed of 5SHY3545L0020 generally does not need to be considered. Therefore, selecting a low-end machine with A/D conversion, D/A conversion, addition and subtraction, and data transmission functions can meet the requirements; In engineering projects with complex control and high requirements for control functions (such as PID operation, closed-loop control, communication networking, etc.), mid-range or machine (mainly used for large-scale process control, distributed control systems with full PLC, and automation of the entire factory) can be selected based on the control scale and complexity.
IGCT Integrated Gate Commutated Thyristor is a new type of power semiconductor switching device developed for medium voltage frequency converters and used in giant power electronic complete sets of equipment (Integrated Gate Commutated Thyristor=Gate Commutated Thyristor+Gate Unit). Proposed by ABB in 1997. IGCT enables the converter device to
Significant progress has been made in power, reliability, switching speed, efficiency, cost, weight, and volume, bringing new leaps to power electronics equipment. IGCT integrates GTO chips with anti parallel diodes and gate driver circuits, and then connects them with the gate driver in a low inductance manner on the periphery. It combines the advantages of stable turn off capability of transistors and low on state loss of thyristors, and exhibits the performance of thyristors during the conduction stage and the characteristics of transistors during the turn off stage. IGCT has the characteristics of high current, high blocking voltage, high switching frequency, high reliability, compact structure, and low conduction loss. Moreover, it has low manufacturing cost and high yield, and has been widely used in power system grid devices (100MVA) and medium power industrial drive devices (5MW). IGCT has been successfully applied in the field of medium voltage frequency converters for 11 years (until 2009). Due to its high-speed switching capability, IGCT does not require buffer circuits, requiring fewer power components and greatly improving operational reliability.
IGCT combines the high-speed switching characteristics of IGBT (Insulated Gate Bipolar Transistor) with the high blocking voltage and low conduction loss characteristics of GTO (Gate Turn Off Thyristor). Generally, the trigger signal is transmitted to the IGCT unit through optical fiber. In the phase module of the active rectifier unit of ACS6000, each phase module is composed of IGCT, diode, and clamp capacitor, and is powered by an independent gate power supply unit GUSP.
