Technical Specifications

Key Design Features

1. Press-Fit Technology:
• 5SDF1045H0002 uses press-fit pins instead of soldered connections, eliminating thermal fatigue and improving reliability in high-vibration environments (e.g., traction drives).
2. Dual-Channel Drive Architecture:
• 3BHL000986P3002 supports parallel IGBT operation with synchronized switching, enabling scalable power systems (e.g., 2,000A+ configurations via module paralleling).
3. Advanced Protection Circuitry:
• Desaturation detection (Vce monitoring) trips the IGBT within 1μs of overcurrent, preventing catastrophic failure.
• Integrated snubber capacitors (22nF/1.2kV) reduce voltage spikes during switching, extending module lifespan.
4. Thermal Management Integration:
• Module features an embedded NTC thermistor for real-time temperature monitoring, with the driver unit providing proportional cooling fan control (when paired with external fans).

Application Scenarios

1. Medium-Voltage Drives:
• Industrial motors (3-10kV) in mining, oil & gas, and water treatment plants.
• Example: 5MW pump drive systems with 6-pulse inverter topologies.
2. Renewable Energy Inverters:
• Wind turbine converters (2-5MW) for grid connection, solar power plant central inverters (1-3MW).
• Supports transformerless designs with high-efficiency PWM modulation.
3. High-Power UPS Systems:
• Critical infrastructure (data centers, hospitals) requiring uninterruptible power with low total harmonic distortion (THD <3%).
4. Railway Traction Systems:
• Electric locomotive drives (1.5-3kV DC input), subway propulsion systems with regenerative braking capabilities.
5. HVDC & Power Grid Equipment:
• Flexible AC transmission systems (FACTS), static var compensators (SVC), and high-voltage DC converters.
