3. Working Principle
Structural Features
Integrating a gate drive and symmetric thyristor chips, it combines the high-voltage and high-current capabilities of thyristors with the IGBT-style gate turn-off characteristics. No external turn-off circuit is required, which simplifies the design and improves reliability.
Operating Mechanism
- Turn-on: Applying a positive voltage to the gate enables the fast turn-on of the device with a low on-state voltage drop, suitable for medium and high-power transmission.
- Turn-off: Applying a reverse voltage to the gate achieves fast turn-off through gate commutation with a turn-off time of approximately 80-120μs, adapted to medium and high-frequency conversion.
- Protection Functions: Built-in overcurrent, overvoltage and overheating protection, which cooperates with the drive circuit to realize fast fault response and status feedback, improving system safety.
Key Characteristics
Adopting transparent anode technology and improved irradiation process, it reduces the storage time and gate charge requirement, supports snubberless turn-off with high di/dt, and is adapted to medium and high-frequency operating conditions.
