Fuji 6MBP20RH060 IGBT Module | Compact CIB for High-Efficiency Motor Drives
The **Fuji Electric 6MBP20RH060** is a highly integrated Power Integrated Module (PIM) engineered for compact and efficient power conversion systems. This module consolidates a complete three-phase power stage—including a converter, inverter, and brake chopper—into a single, thermally efficient package. Designed for low-power applications, the **6MBP20RH060** is the go-to solution for engineers developing variable frequency drives (VFDs), servo systems, and uninterruptible power supplies where space, assembly cost, and reliability are paramount.
Application Value Across Industrial Automation
The true strength of the **6MBP20RH060** lies in its ability to solve specific engineering challenges across various applications. Its integrated design delivers tangible benefits beyond simple component consolidation.
- Compact Motor Drives: For applications like conveyor belts, pumps, and ventilation systems, drive size and cost are critical constraints. The all-in-one nature of this CIB module drastically reduces PCB footprint and simplifies the bill of materials. This leads to a smaller, more cost-effective, and reliable final product, a key advantage in competitive industrial motor drive markets.
- Servo Control Systems: Precision motion control requires rapid dynamic response, including fast braking. The integrated brake chopper circuit in the **6MBP20RH060** is essential for managing regenerative energy during deceleration, preventing DC-link overvoltage without needing an external braking unit. This ensures system stability and protects other components.
- Uninterruptible Power Supplies (UPS): In small to mid-size UPS systems, efficiency directly impacts battery runtime. The module's low-loss IGBTs and optimized freewheeling diodes minimize energy waste in both inverter and rectifier operations, maximizing system uptime during critical power outages.
Technical Deep Dive: The Engineering Behind the Performance
Two core technical features define the exceptional value of the Fuji 6MBP20RH060.
Integrated Converter-Inverter-Brake (CIB) Topology
This module is built on a Converter-Inverter-Brake architecture. It integrates a three-phase diode bridge for AC-to-DC rectification, a full three-phase IGBT bridge for the DC-to-AC inverter, and an IGBT with an anti-parallel diode for the brake chopper. This integration minimizes stray inductance between stages, reducing voltage overshoot and simplifying EMI management. For designers, this means fewer external components, a simplified assembly process, and enhanced system-level reliability.
Low Conduction Loss (Vce(sat)) Technology
Fuji Electric employs advanced trench-gate and field-stop technologies to achieve a low collector-emitter saturation voltage (Vce(sat)). A lower Vce(sat) directly translates to reduced conduction losses, which is the primary source of heat in many motor drive applications. This superior thermal performance allows for the use of smaller heatsinks, increases power density, and ultimately improves the overall energy efficiency of the end system.
Selection Advice: CIB Module vs. Discrete Solution
Engineers often weigh the benefits of an integrated module like the 6MBP20RH060 against a solution built from discrete components. While a discrete approach offers layout flexibility, it comes with increased design complexity, a larger physical footprint, and more potential points of failure. For low-power drives (typically under 3kW), the 6MBP20RH060 CIB module offers a clear advantage by streamlining procurement, simplifying thermal management onto a single baseplate, and accelerating time-to-market. It is the optimal choice for designs prioritizing compactness and manufacturing efficiency.

Frequently Asked Questions (FAQ)
-
How does the integrated NTC thermistor add value?
The built-in NTC thermistor provides real-time temperature feedback directly from the module's substrate. This allows the system controller to implement precise over-temperature protection, preventing catastrophic failure and enhancing long-term operational reliability without the need for an external sensor.
-
Is this module suitable for high-frequency switching applications?
The 6MBP20RH060 is optimized for low- to medium-frequency applications, typically found in motor drives (e.g., 2-10 kHz). While its switching losses are well-controlled for this range, applications requiring very high frequencies (>20 kHz) might benefit from specialized IGBTs or other semiconductor technologies. Please review the datasheet's switching characteristics for your specific requirements.
