Product Name
5SHY3545L0014 3BHE023784R0001 Industrial-Grade High-Power IGBT Power Module for Medium-Voltage Inverters
(Referred to as “5SHY3545L0014 IGBT Power Module” for short, it belongs to ABB’s Medium-Voltage Inverter Power Component portfolio. Tailored for high-power industrial drive systems—such as steel mill rolling mill inverters, mining conveyor drives, and power plant fan/pump inverters—it functions as the core power conversion unit. It converts DC power to adjustable AC power (for motor speed control) via insulated gate bipolar transistor (IGBT) technology, delivering high efficiency and stable power output while withstanding harsh industrial operating conditions.)
2. Product Description
The 5SHY3545L0014 3BHE023784R0001 IGBT power module addresses the demand for high-power density, reliable power conversion in medium-voltage industrial inverters (e.g., 6.6kV/10kV inverter systems for steel rolling mill main motors, high-torque mining conveyor inverters, and energy-efficient power plant auxiliary motor drives). It adopts a modular IGBT half-bridge topology—integrating two high-voltage IGBT chips, anti-parallel freewheeling diodes, and gate driver circuits—with a rated current of 450A (rms) and a maximum blocking voltage of 3.3kV, enabling efficient DC-AC power conversion with a typical efficiency of ≥98.5% at full load.
This design effectively resolves key challenges in medium-voltage power conversion: it minimizes power loss via low-conduction-loss IGBT chips, ensures thermal stability through optimized heat dissipation, and resists voltage transients and electromagnetic interference (EMI) via robust packaging. Its core advantages include:
- High-Power Density & Efficiency: Utilizes ABB’s 4th-generation high-voltage IGBT chips with a low on-state voltage (Vce(sat) ≤2.2V at 450A) and fast switching speed (10kHz max switching frequency). The half-bridge topology enables compact integration into inverter cabinets—reducing the overall footprint by 20% compared to discrete IGBT solutions—while maintaining high conversion efficiency (≥98.5% at rated load), lowering energy consumption for large-scale industrial drives.
- Robust Thermal Management: Features a direct-bonded copper (DBC) substrate with high thermal conductivity (≥200W/m·K) and a ceramic-insulated package (Al₂O₃) that evenly distributes heat. The module supports both forced-air and water-cooling systems (compatible with ABB’s standard inverter cooling units) and operates reliably at a maximum junction temperature (Tj) of 150℃—preventing thermal overload even during peak load conditions (e.g., 150% rated current for 1min).
