The SKIIP35NAB126V1 is a highly integrated intelligent power module (IPM) from Semikron. It's part of their SKIIP (Semikron Integrated Intelligent Power) series, known for integrating various power semiconductor components and control circuitry into a compact package. This specific module is designed for three-phase inverter applications, commonly found in motor drives, renewable energy systems (such as solar inverters), and uninterruptible power supplies (UPS).

Applications:

• Three-phase motor drives for industrial automation.
• Solar inverters for residential and commercial photovoltaic systems.
• Uninterruptible power supplies (UPS) for critical equipment.
• Air conditioning systems.
• Welding equipment.

Features:

• Integrated gate drivers: Simplifies the driving circuitry, reducing component count and PCB space.
• Short-circuit protection: Protects the module from damage due to overcurrent conditions.
• Over-temperature protection: Shuts down the module if the temperature exceeds a safe limit, preventing thermal runaway.
• Under-voltage lockout (UVLO): Prevents the module from operating when the supply voltage is too low, ensuring reliable operation.
• Three-phase inverter topology: Designed for efficient conversion of DC power to three-phase AC power.
• Low thermal resistance: Enables efficient heat dissipation, improving reliability and extending lifespan.
• CIB (Converter Inverter Brake) functionality: Includes braking chopper for dynamic braking applications.
