Product Name

Core Functions and Technical Positioning

1. Device Type and Technical Characteristics

• IGCT Technical Advantages: Combines the fast switching characteristics of IGBTs (Insulated Gate Bipolar Transistors) with the high-voltage and large-current carrying capacity of thyristors, suitable for scenarios such as high-voltage frequency converters, DC transmission, and industrial motor drives.
• Triac Structure: Adopts a three-terminal triac design, enabling bidirectional conduction and precise control of alternating current, supporting functions like motor speed regulation and heating system adjustment.
• High Power Density: Achieves a rated current of up to 47A and a rated voltage of 1400V in a compact package (e.g., 100mm×60mm×40mm), meeting high-power requirements.

2. Core Functions

• Motor Control: Adjusts the firing angle to control the speed and torque of high-voltage AC motors, widely used in industrial equipment such as water pumps, fans, and compressors.
• Power Conversion: Serves as a core component in frequency converters, enabling AC/DC/AC energy conversion and supporting grid-connected control of renewable energy generation (e.g., wind power, photovoltaics).
• System Protection: Integrates overcurrent and overheating protection functions, with built-in sensors to monitor module status in real-time, ensuring safe operation of equipment.
