FS450R12KE3/AGDR-71C
Product Name
ABB FS450R12KE3/AGDR-71C Integrated IGBT Power & Gate Driver Module Assembly for Industrial Drives(The naming follows the tandem logic of power semiconductor systems:
- “FS450R12KE3″: Infineon’s high-power IGBT module—”FS” denotes the Fast Switching series, “450” indicates 450A rated current, “R12” specifies 1200V breakdown voltage, and “KE3” is the performance grade.
- “AGDR-71C”: ABB’s dedicated gate driver module—”AGDR” stands for “Advanced Gate Driver for Rectifiers/Inverters,” and “71C” designates compatibility with 1200V, 400–600A IGBTs.
- “Integrated IGBT Power & Gate Driver Module Assembly”: Highlights the integrated design—pairing the IGBT (power switch) with the gate driver (control/protection unit) to eliminate compatibility issues and simplify system integration.
This assembly acts as the “power conversion core” of industrial drives, converting DC power to variable-frequency AC for motor control while ensuring safe, efficient switching.)
2. Product Description
The FS450R12KE3/AGDR-71C is an industrial-grade integrated power module assembly engineered for medium-power industrial drives (200–500kW). It addresses critical challenges in power conversion: IGBT switching loss, overcurrent/overvoltage damage, and driver-IGBT compatibility—by combining Infineon’s low-loss IGBT with ABB’s adaptive gate driver. This tandem integration delivers high-efficiency power switching, multi-layer protection, and seamless drive system compatibility, making it indispensable for:
- Industrial Drives: Powering ABB ACS880/ACS6000 series drives in conveyor systems, enabling variable speed control with <2% total harmonic distortion (THD).
- Renewable Energy: Inverters for 100kW solar PV systems, converting DC panel output to grid-compatible AC with 98.5% efficiency.
- Marine Propulsion: Medium-voltage drives for auxiliary motors, with ruggedness to withstand saltwater corrosion and vibration.
- Metal Processing: Induction heating systems, where precise IGBT switching (up to 60kHz) maintains temperature stability (±5°C) for steel annealing.
Key Functional Advantages
-
Low-Loss IGBT & Adaptive Gate Drive for High EfficiencyThe FS450R12KE3 IGBT uses Infineon’s TrenchStop 3 technology, reducing on-state voltage to 1.8V (typ) and switching losses by 30% vs. legacy IGBTs . The AGDR-71C driver adapts gate current (5–20A) to load conditions—minimizing switching loss at light loads and ensuring fast turn-off at heavy loads. Combined, the assembly achieves 98.5% efficiency in 300kW drives, cutting energy consumption by 12,000kWh/year for 24/7 operation .
-
Multi-Layer Protection to Prevent IGBT DamageThe AGDR-71C integrates 6+ protection mechanisms:
- Short-Circuit Protection: Detects IGBT short circuits in <1µs, triggers soft turn-off (10V/µs voltage slew rate) to avoid voltage spikes, and locks out PWM signals .
- Overvoltage/Overcurrent Protection: Clamps DC link voltage at 1320V (110% of rated 1200V) and trips
