TOSHIBA MP6752 IGBT Module

Toshiba MP6752 | Integrated CIB Module for Advanced Motor Control

The Toshiba MP6752 is a highly integrated Power Integrated Module (PIM) designed to streamline the development of compact and efficient power conversion systems. As a Converter-Inverter-Brake (CIB) module, it combines a three-phase diode bridge rectifier, a brake chopper IGBT with a free-wheeling diode, and a full three-phase IGBT inverter bridge into a single, compact package. This all-in-one approach is engineered for applications like AC motor drives, servo controllers, and uninterruptible power supplies where space, reliability, and assembly efficiency are critical design drivers.

Unpacking the Value: The CIB Advantage

The core strength of the Toshiba MP6752 lies in its CIB topology. By consolidating three essential power stages, system designers can dramatically reduce the bill of materials (BOM), minimize PCB footprint, and simplify thermal management. Instead of sourcing, mounting, and connecting separate rectifier bridges, brake choppers, and inverter stages, you get a pre-optimized, factory-tested solution. This not only accelerates time-to-market but also significantly reduces assembly complexity and potential points of failure, leading to a more robust and cost-effective end product.

Core Technology for Superior Performance

• Low Loss IGBT Technology: The MP6752 leverages Toshiba's advanced IGBTs, which are optimized for low saturation voltage (Vce(sat)). This directly translates to lower conduction losses during operation, meaning less energy is wasted as heat. The benefit is twofold: higher overall system efficiency and a reduced requirement for bulky, expensive heatsinks, further contributing to a compact system design.
• Soft & Fast Recovery Diodes: Paired with the IGBTs are optimized free-wheeling diodes (FWDs) featuring soft and fast recovery characteristics. This minimizes reverse recovery losses and reduces voltage overshoots during switching, which simplifies EMC filter design and enhances the overall reliability of the motor drive or inverter.
• Integrated NTC Thermistor: For robust system protection, the module includes an on-chip NTC thermistor. This allows for precise, real-time temperature monitoring of the module's substrate, enabling the control system to implement over-temperature protection and ensure the long-term operational lifespan of the power stage.

MP6752 in Action: Application-Specific Benefits

• Compact AC Motor Drives: For variable frequency drives (VFDs), the Toshiba MP6752 allows for an exceptionally small form factor. Its integrated nature is ideal for decentralized drives or servo systems where every millimeter of space counts, without compromising on power handling or efficiency.
• High-Performance Servo Control: The module's low-loss switching and integrated brake chopper are critical for servo applications. The brake circuit efficiently dissipates regenerative energy during rapid deceleration, while the clean switching performance enables precise current control for accurate positioning and smooth motor operation.
• Uninterruptible Power Supplies (UPS): In UPS systems, reliability is non-negotiable. The reduced component count and simplified assembly offered by the MP6752 inherently increase the mean time between failures (MTBF) compared to a complex discrete solution, ensuring critical loads remain protected.

Making the Right Choice: MP6752 vs. Discrete Solutions

Engineers often weigh the benefits of an integrated module like the Toshiba MP6752 against a discrete design. While discrete components offer maximum layout flexibility, they demand significantly more design effort in PCB layout, thermal interfacing, and component sourcing. The MP6752 is the superior choice for projects prioritizing speed-to-market, space efficiency, and manufacturing simplicity. For standard motor drive and power conversion applications up to its power rating, the pre-engineered integration of this CIB module provides a clear advantage. For more specialized or higher power designs, you may want to explore more IGBT modules with different configurations.
