5SHY4045L0001 Asymmetric thyristor IGCT (Integrated Gate Reversing Thyristor) module

• Basic Parameters
  • Rated Voltage: 4500V
  • Rated Current: 4000A
• Performance Features
  • Fast Switching: Adopting IGCT chip technology, multi-layer semiconductor structure, and low-inductance packaging design, the switching speed can reach the nanosecond level, enabling switching on and off within microseconds, which can reduce switching losses and voltage overshoot.
  • Low Loss: By improving the gate structure and materials, the voltage drop of the module during high-voltage conduction is significantly reduced, saving 15%-25% energy compared with traditional thyristors. At the same time, using transparent anode technology, the turn-off process does not require complex snubber circuits, which can reduce switching energy loss.
  • High Reliability: Its key circuits adopt a dual backup design, so a single point of failure will not affect the system operation. Moreover, the operating temperature range covers -40°C to +85°C, and the anti-electromagnetic interference capability complies with IEC 61850-3 standards, making it suitable for harsh environments such as offshore wind power platforms and smelting workshops.
  • Optimized Structure: A freewheeling diode with good dynamic characteristics is integrated on one chip. It also adopts a buffer structure and shallow emitter technology, reducing its dynamic loss by about 50%, and organically combining the low on-state voltage drop of thyristors, high blocking voltage, and stable switching characteristics of transistors.
• Application Fields
  • Industrial Drives: It can be used to drive high-voltage frequency converters, precisely adjust the speed of pump and compressor loads, and is widely used in industries such as petroleum refining and mining.
  • New Energy Power Generation: As a core component of wind power converters, it can realize bidirectional energy conversion between generators and the power grid. It can also be used in photovoltaic inverter scenarios to achieve efficient DC-AC conversion and improve the efficiency of new energy power generation.
  • Power Systems: In high-voltage direct current transmission projects, this module can serve as a converter valve component to undertake AC-DC conversion tasks. It is also suitable for static var compensators, which can stabilize voltage fluctuations and improve grid resilience.
