## EVL31-060 | 600V 60A CIB IGBT Module for High-Efficiency Motor Control
The EVL31-060 is a highly integrated Power Integrated Module (PIM) engineered to streamline the design and enhance the performance of low-to-medium power motion control systems. By co-packaging a three-phase input rectifier, a brake chopper, and a three-phase inverter into a single, thermally efficient housing, this module provides a robust foundation for compact and reliable power conversion.

- Advanced Field-Stop Trench IGBTs: Utilizes 600V Field-Stop Trench Gate IGBT technology, which masterfully balances low conduction losses (Vce(sat)) and optimized switching performance for superior system efficiency.
- Integrated NTC Thermistor: Includes an on-board NTC thermistor, enabling precise, real-time temperature monitoring for implementing sophisticated thermal protection and preventing catastrophic failure.
- Superior Thermal Management: Built on an Alumina (Al2O3) Direct Bonded Copper (DBC) substrate, ensuring low thermal resistance from junction to case and promoting excellent long-term reliability and power cycling capability.
Technical Deep Dive: Engineering for Efficiency and Reliability
The performance of the EVL31-060 is rooted in its intelligent silicon and packaging design. Two features, in particular, empower engineers to build more competitive systems.
The Core of Performance: Field-Stop Trench Technology
At the heart of the EVL31-060 inverter and brake stages lies advanced Field-Stop Trench IGBT technology. Unlike older planar IGBTs, the trench gate structure allows for higher cell density, which significantly lowers the on-state voltage drop, or VCE(sat). This directly translates to lower conduction losses and less waste heat. The addition of a "field-stop" layer allows for a thinner silicon die, which reduces switching losses, particularly the turn-off energy (Eoff). This combination is critical for achieving high efficiency in systems that operate across a wide range of speeds and loads.
Integrated Thermal Feedback Loop
The inclusion of an NTC thermistor is more than a convenience; it is a critical system-level safety feature. This integrated sensor provides a direct feedback path to the system's microcontroller, allowing for continuous monitoring of the module's internal temperature. This data enables intelligent thermal management strategies, such as dynamically derating the output current or triggering a graceful shutdown if an over-temperature condition is detected, safeguarding both the drive and the motor.
Application Focus: Where the EVL31-060 Excels
The EVL31-060 CIB module is purpose-built for applications where space, assembly cost, and efficiency are paramount design drivers.
- Variable Frequency Drives (VFDs): For AC motor drives up to approximately 11 kW, the EVL31-060 provides the complete power stage. Its high level of integration simplifies the manufacturing process, while its efficiency helps meet energy standards like IE3 and IE4. The brake chopper is essential for managing regenerative energy during motor deceleration, a common scenario in conveyor and hoisting applications.
- Robotic Servo Drives: In precision motion control, the fast and soft switching characteristics of the module's IGBTs are key to achieving the high dynamic response needed. The low thermal resistance and compact size of the module enable the development of smaller, more powerful servo drives for multi-axis robotics and CNC machinery.
- Uninterruptible Power Supplies (UPS): The module's robust rectifier and high-efficiency inverter make it an excellent choice for the power conversion stage in online UPS systems, ensuring reliable power with minimal energy loss.

Engineer's FAQ for the EVL31-060
What are the primary benefits of the CIB topology in this module?
The main advantage is system integration. A CIB module like the EVL31-060 consolidates the AC-DC rectifier, DC-link braking chopper, and DC-AC inverter into a single, optimized package. This reduces sourcing complexity from three or more component types to just one, minimizes PCB real estate, and simplifies the assembly process. Furthermore, the thermal pathways are engineered within the module for balanced heat dissipation across all stages.
What are the key gate drive considerations for the EVL31-060?
For optimal performance and reliability, a dual-supply gate drive is highly recommended, typically +15V for turn-on and a negative voltage (e.g., -5V to -10V) for turn-off. The negative gate bias provides a strong defense against parasitic turn-on caused by high dv/dt during the switching of other devices in the bridge, a common failure mode. A well-implemented robust gate drive design with short, low-inductance traces is critical to fully leveraging the module's performance.
