Fuji Electric 7MBP100RA060 | Compact 600V, 100A PIM for High-Performance Drives
The Fuji Electric 7MBP100RA060 is a high-integration Power Integrated Module (PIM) designed to streamline the development of compact and efficient power conversion systems. By co-packaging a three-phase inverter bridge and a brake chopper circuit, this module provides a robust, all-in-one solution for engineers working on low-to-medium power applications. It is engineered to reduce system complexity, minimize board space, and enhance thermal performance.
- Voltage and Current Rating: 600V / 100A, ideal for 200-240V AC line applications.
- Integrated 7-in-1 Topology: Features a full three-phase IGBT bridge, a brake chopper IGBT with an anti-parallel freewheeling diode (FWD), and an NTC thermistor for real-time temperature monitoring.
- Optimized VCE(sat): Exhibits a low collector-emitter saturation voltage, which directly translates to lower conduction losses and improved overall system efficiency.
- Compact P-610 Package: Enables high power density designs where physical space is a critical constraint.
Application Scenarios & Engineering Value
The integrated architecture of the Fuji Electric 7MBP100RA060 delivers tangible benefits across several demanding applications. It’s not just a component; it’s a solution to common engineering challenges.
- AC & DC Servo Drives: In precision motion control and robotics, space is at a premium. The compact footprint of this PIM allows for smaller, more integrated drive designs. The integrated brake chopper efficiently manages regenerative energy during deceleration, eliminating the need for a separate braking unit and simplifying the overall system. This makes it an excellent choice for powering robotic servo drives.
- General Purpose Inverters: For designers of variable frequency drives (VFDs), the 7-in-1 configuration drastically reduces component count and assembly complexity. This leads to lower manufacturing costs, simplified PCB layouts with reduced parasitic inductance, and increased reliability compared to discrete-based solutions.
- Uninterruptible Power Supplies (UPS): System reliability is paramount in UPS applications. The 7MBP100RA060 includes an on-board NTC thermistor, allowing for precise temperature feedback to the control system. This enables robust over-temperature protection, ensuring stable operation and prolonging the service life of the UPS.
Technical Deep Dive: The PIM Advantage
The core value of a Power Integrated Module (PIM) like the 7MBP100RA060 lies in its intelligent integration. By consolidating seven semiconductor devices into a single thermally optimized package, Fuji Electric addresses several system-level challenges. The proximity of the IGBTs and diodes minimizes stray inductance within the module, which helps to reduce voltage overshoots during high-speed switching events. This cleaner switching behavior can simplify the design of external snubber circuits and improve electromagnetic compatibility (EMC).
Furthermore, the module's chip technology is carefully balanced. The specified VCE(sat) of 1.7V (typical at 100A) represents a deliberate trade-off between conduction and switching losses. This optimization makes the module highly effective in applications operating at PWM frequencies up to ~15 kHz, typical for motor drives, where both loss mechanisms are significant contributors to the overall thermal load.

Frequently Asked Questions (FAQ)
What are the primary thermal management considerations for this module?
Effective thermal management is crucial for reliability. The module must be mounted on a flat, clean heatsink using a high-quality thermal interface material (TIM). The integrated NTC thermistor should be connected to your controller's ADC input to actively monitor module temperature and trigger a fault or power reduction if it exceeds safe limits. Understanding the impact of thermal resistance (Rth) is key to a robust design.
How should the gate drive circuit be designed for the 7MBP100RA060?
A standard gate drive voltage of +15V for turn-on and -5V to -10V for turn-off is recommended. A negative gate voltage ensures a robust off-state, especially in noisy environments, preventing parasitic turn-on. Each IGBT gate should have its own series gate resistor to control switching speed and dampen oscillations. For more advanced topics, explore our guide on robust IGBT gate drive design.
