3、 Key technical characteristics and advantages
Integrated gate driver design: IGCT technology integrates the gate driver circuit with the thyristor chip, eliminating the need for complex external turn off buffer circuits. This not only simplifies the system topology, but also reduces parasitic inductance, reduces circuit losses, and improves system reliability.
Balancing high-speed switching and low loss: Compared to traditional thyristors, its switching speed is increased by 3-5 times, which can meet the needs of high-frequency power conversion; At the same time, the on state voltage is low, and the on state loss is reduced by 5% -8% compared to traditional thyristors of the same specification, balancing high speed and efficiency characteristics.
High power density and compact packaging: Adopting SEMITRANS 2 packaging technology, high voltage and high current output can be achieved in a small volume, with a power density of 12W/cm ³, which can significantly reduce the size of power conversion equipment and adapt to industrial scenarios with limited space.
Excellent anti-interference and stability: The combination design of ceramic insulation substrate and metal shell has good thermal conductivity and vibration resistance, and can withstand electromagnetic interference, temperature fluctuations, and mechanical vibrations in industrial environments. The mean time between failures (MTBF) exceeds 50000 hours.
Complete built-in protection mechanism: integrated gate trigger protection, reverse voltage protection, overheating protection, and overcurrent protection functions. When abnormal working conditions are detected, it can quickly respond within 10 μ s, cut off the main circuit or limit the current, avoiding damage to the module and backend equipment.
4、 Typical application industries and scenarios
Industrial variable frequency speed regulation system: As the core component of the inverter bridge in medium and high-power motor variable frequency drives (such as fans, pumps, compressors), it realizes the variable frequency conversion of AC power, improves speed regulation accuracy with high-speed switch characteristics, and reduces equipment energy consumption with low loss characteristics.

Performance testing: Every six months, the on state voltage and insulation resistance are tested using a multimeter. If the on state voltage deviation exceeds ± 10% or the insulation resistance is below 100M Ω, the module should be replaced in a timely manner.
Troubleshooting: When a malfunction occurs, first disconnect the main power supply and use an oscilloscope to check if the gate trigger signal is normal; If the module is damaged, anti-static measures should be taken during replacement (wearing an anti-static wristband) to avoid static electricity breakdown of the chip.
