Infineon FS100R12KT4G | Advanced T-NPC Module for High-Efficiency Inverters
The Infineon FS100R12KT4G is not just another power module; it is a highly specialized solution engineered for advanced power conversion systems. As a 1200V, 100A IGBT module in the robust EconoDUAL™ 3 package, its primary distinction lies in its integrated T-NPC topology. This design is purpose-built to empower engineers in developing next-generation solar inverters, uninterruptible power supplies (UPS), and industrial drives that demand superior efficiency and power quality.
Technical Deep Dive: The T-NPC Advantage
Understanding the core technologies within the FS100R12KT4G reveals its true value in demanding applications.
- Optimized Three-Level T-NPC Topology: Unlike standard 2-level inverters that switch between two voltage levels (e.g., +Vdc and -Vdc), this module enables a three-level output (+Vdc, 0, -Vdc). This architecture significantly reduces the voltage stress on the switching devices and produces an output waveform with much lower harmonic distortion. For the system designer, this translates directly to smaller, lighter, and more cost-effective output filters and improved overall system efficiency. This is a key feature of modern multilevel inverter topology designs.
- IGBT4 Trench Field-Stop Technology: The heart of the FS100R12KT4G features Infineon's proven IGBT4 Trench Field-Stop chips. This technology achieves an exceptionally low collector-emitter saturation voltage (Vce(sat)). A lower Vce(sat) minimizes the power dissipated as heat during the on-state, directly reducing conduction loss. This thermal efficiency allows for smaller heatsinks, higher power density, and enhanced system reliability over its operational lifetime.
Application-Specific Benefits of the FS100R12KT4G
The theoretical advantages of the T-NPC topology become tangible benefits when applied to specific industrial challenges:
- Solar Inverters: The higher conversion efficiency enabled by the three-level architecture maximizes the energy harvested from photovoltaic arrays. The cleaner output sine wave reduces grid-interface filtering requirements, improving the Levelized Cost of Energy (LCOE).
- Uninterruptible Power Supplies (UPS): For data centers and critical industrial processes, power quality is paramount. The low-distortion output of an inverter built with the Infineon FS100R12KT4G ensures cleaner, more reliable power to sensitive loads, improving uptime and preventing equipment damage.
- Industrial Motor Drives: The smoother output voltage waveform results in reduced torque ripple and lower acoustic noise from the motor. It also places less dv/dt stress on the motor winding insulation, which can significantly extend the motor's service life and reduce maintenance cycles.

Selection Guidance: FS100R12KT4G vs. Standard 6-Pack Modules
Engineers often face a choice between a specialized module like the FS100R12KT4G and a conventional 6-pack IGBT module for a three-phase inverter. While a 6-pack is versatile for standard 2-level inverters, the FS100R12KT4G is the superior choice for new designs targeting the highest efficiency benchmarks. If your primary design goal is maximum power conversion efficiency, minimal output filtering, and high power quality—as required in solar and UPS applications—the integrated T-NPC topology of this module offers a clear advantage in performance and layout simplification. For general-purpose, cost-sensitive motor drives where basic performance is sufficient, a standard 6-pack might be considered. For a wider selection, you can Explore More IGBT Modules on our website.
Frequently Asked Questions (FAQ)
- What is the main benefit of the integrated NTC thermistor?
The built-in NTC thermistor provides a direct, real-time temperature reading of the module's baseplate. This is critical for implementing over-temperature protection and for sophisticated thermal management algorithms, which ultimately enhance the system's long-term reliability. - Does using a three-level module complicate the gate driver design?
While a three-level topology requires a more complex gate drive and control scheme than a standard 2-level inverter, the benefits often outweigh this complexity. The Infineon FS100R12KT4G's well-defined EconoDUAL™ 3 package simplifies the power layout, and many modern gate driver ICs are available to support multilevel topologies.
