Fuji Electric 7MBP75JB060 | High-Integration CIB Module for Compact Power Systems
The Fuji Electric 7MBP75JB060 is a highly integrated 600V, 75A Power Integrated Module (PIM) designed to streamline the development of low-to-mid-power conversion systems. By consolidating a three-phase rectifier bridge, a brake chopper, and a three-phase inverter into a single, thermally efficient package, this module acts as a complete power stage. It is the go-to solution for engineers developing compact motor drives, servo controllers, and uninterruptible power supplies where reducing component count, minimizing PCB footprint, and accelerating time-to-market are paramount design goals.
Unpacking the Core Technology Advantages
-
All-in-One CIB (Converter-Inverter-Brake) Topology
Technical Principle: The 7MBP75JB060 integrates three distinct power circuits: a diode bridge for AC-to-DC conversion, a 3-phase IGBT bridge for DC-to-AC inversion, and an IGBT with a freewheeling diode for dynamic braking. This CIB configuration eliminates the need for multiple discrete components and complex interconnects on the main power board.
Application Value: This integration dramatically simplifies system design and assembly, leading to a smaller overall product size and lower manufacturing costs. For engineers, this means faster design cycles, reduced parasitic inductance, and improved system reliability by minimizing potential points of failure.

Optimized IGBT and FWD Performance
Technical Principle: The module utilizes Fuji Electric's advanced trench-gate field-stop IGBT technology, which achieves a low saturation voltage (Vce(sat)). This is complemented by soft-recovery Freewheeling Diodes (FWDs) optimized for low reverse recovery losses and reduced voltage overshoot during switching.
Application Value: The low Vce(sat) directly translates to lower conduction losses, reducing the heat generated by the module. This allows for smaller heatsinks and, in some cases, can even enable fanless designs in lower power applications. The soft-recovery FWDs minimize electromagnetic interference (EMI), simplifying EMC filter design and compliance testing.
Multi-Dimensional Application Scenarios
The unique features of the Fuji Electric 7MBP75JB060 deliver tangible benefits across a range of demanding industrial applications:
- General-Purpose Inverters & Small AC Motor Drives: The CIB design drastically shrinks the inverter's physical volume. This allows for the development of more compact variable frequency drives (VFDs) without sacrificing performance or thermal headroom.
- Servo Control Systems: In high-precision robotics and CNC machinery, reliability is key. The integrated protection features and low thermal drift of the 7MBP75JB060 ensure stable and repeatable positioning performance, while the dynamic brake circuit effectively handles regenerative energy during rapid deceleration.
- Uninterruptible Power Supplies (UPS): The module simplifies the power stage of online UPS systems, handling both the rectifier and inverter functions in one component. This enhances power density, a critical factor for data center and commercial UPS applications.
- Automated Guided Vehicles (AGVs): For battery-powered logistics robots, space and efficiency are critical. The compact footprint and high efficiency of this PIM enable longer operational cycles and more payload capacity.

Comparative Analysis & Selection Guidance
Engineers often weigh the Fuji Electric 7MBP75JB060 against a discrete solution comprising a separate rectifier bridge, six individual IGBTs, and a brake chopper. While a discrete approach offers more layout flexibility, it comes at the cost of significantly higher design complexity, a larger PCB area, and increased assembly time. The 7MBP75JB060 is the superior choice for projects where development speed, system compactness, and proven reliability are the primary drivers. For applications requiring custom layouts or extremely high switching frequencies above the module's specified limits, a discrete solution might be considered.

Frequently Asked Questions
-
What kind of gate driver circuit is recommended for the 7MBP75JB060?
A gate driver with short-circuit protection (desaturation detection) and an isolated power supply is highly recommended. The driver should be capable of providing the specified gate-emitter voltage (typically +15V/-5V to -10V) to ensure efficient switching and prevent spurious turn-on.
-
How does the integrated NTC thermistor improve system reliability?
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, throttling back power or initiating a safe shutdown before the IGBTs reach a critical temperature, thereby preventing catastrophic failure and extending the system's lifespan.
