Advantages of Insulated Gate Bipolar Transistor (IGBT)

Core Advantages
High Input Impedance: Similar to MOSFETs, IGBTs are voltage-driven devices, with the gate consuming almost no current, making the driving circuit simple and low-power.

Low Driving Power: Only milliwatt-level driving power is required, much lower than traditional BJTs, conducive to energy-efficient design.

Reduced Conduction Voltage Drop: Using the conductivity modulation effect, the on-state saturation voltage (VCE(sat)) is only 1–3V, significantly lower than MOSFETs of the same voltage rating, thereby reducing conduction loss.

High Switching Speed: Operating frequency can reach 1–20 kHz, suitable for high-frequency inverters, motor drives, and other scenarios.

Large Power Capacity: A single module can support up to 6500V/600A, suitable for high-voltage, high-current applications such as new energy vehicles, rail transit, and industrial variable frequency drives.

Compact Structure and High Reliability: Modular packaging (such as integration with fast recovery diodes, FWD) facilitates system integration and enhances overall stability.
