EW EW32F62BCW | Integrated CIB Module for Compact Power Conversion
The EW32F62BCW is a highly integrated Power Integrated Module (PIM) designed to streamline the development of three-phase power conversion systems. By combining a three-phase rectifier, a brake chopper, and a three-phase inverter into a single, thermally efficient package, this IGBT integration module radically simplifies system design. It is engineered specifically for engineers and designers working on compact motor drives, uninterruptible power supplies (UPS), servo controllers, and other industrial automation applications where space, assembly cost, and reliability are critical design drivers.
Technical Deep Dive: Why the EW32F62BCW Excels
The performance of the EW32F62BCW is rooted in its intelligent topology and advanced semiconductor technology. Two key features stand out:
- All-in-One CIB Topology: The core value of the EW32F62BCW lies in its Converter-Inverter-Brake (CIB) configuration. This eliminates the need for multiple discrete components, significantly reducing PCB complexity, minimizing stray inductance between power stages, and shrinking the overall system footprint. For designers, this translates to faster development cycles, lower assembly costs, and improved electromagnetic compatibility (EMC) performance.
- Low Vce(sat) for High Efficiency: This module utilizes advanced trench-gate field-stop IGBTs, which are optimized for a low collector-emitter saturation voltage (Vce(sat)). This characteristic directly reduces conduction loss during operation, leading to higher overall system efficiency. The practical benefit is less waste heat, which allows for smaller heatsinks and enhances the system's long-term reliability by lowering operating temperatures.

Application-Specific Value Proposition
The EW32F62BCW is not just a component; it's a solution tailored for specific industrial challenges:
- Variable Frequency Drives (VFDs): In motor control, the integrated brake chopper provides a ready-made solution for managing regenerative energy during deceleration, protecting the DC bus from overvoltage without requiring external chopper circuits. This simplifies the design and improves the dynamic performance of the drive.
- Uninterruptible Power Supplies (UPS): For online UPS systems, the reliability of the power stage is paramount. The EW32F62BCW, as a single factory-tested unit, offers higher reliability and a more predictable thermal performance compared to a solution built from dozens of discrete parts, ensuring greater uptime.
- Servo Drives: Precision and fast response are key in servo applications. The low internal inductance of the EW32F62BCW module enables cleaner switching and faster control loop response, contributing to more accurate positioning and motion control.
- Welding Equipment: The module's robust thermal design and high integration level make it ideal for inverter-based welding power sources, where compact size and the ability to handle pulsed power loads are essential.
Frequently Asked Questions (FAQ)
- What is the primary benefit of the integrated NTC thermistor?The built-in NTC thermistor provides real-time temperature feedback directly from the module's baseplate. This allows the system controller to implement precise over-temperature protection, preventing thermal runaway and significantly enhancing the operational safety and lifespan of the IGBT module.
- Is the EW32F62BCW suitable for paralleling to achieve higher current?CIB modules like the EW32F62BCW are generally designed for single-module operation within their specified current rating. Paralleling these highly integrated modules can be complex due to potential current-sharing imbalances. For applications requiring higher power, we recommend exploring our dedicated high-current half-bridge or six-pack modules.
