4-IGBT Inverter Power Card

High-Speed Switching | Robust Power Handling | Industrial Reliability

The 4-IGBT Card is a dedicated power-stage module engineered for inverter-based welding machines, UPS systems, motor drives, and other high-current DC–AC or AC–DC conversion applications. Featuring four matched Insulated Gate Bipolar Transistors (IGBTs), this card provides efficient, low-loss switching and precise control under heavy-load conditions.


🔧 Key Features:

  • Quad-IGBT Configuration – Four high-current IGBTs in a bridge or half-bridge layout for efficient power conversion

  • 🌡️ Low Thermal Resistance – Thick copper tracks and mount-for-heatsink pads ensure rapid heat dissipation

  • 🔒 Integrated Gate Drivers – Onboard gate driver circuits with adjustable dead-time control optimize switching performance

  • 🛡️ Protection Circuits – Built-in overcurrent, overvoltage, and short-circuit detection for safe operation

  • 🔌 Standard High-Current Terminals – Robust screw or bus-bar connections for DC bus and load wiring

  • 🧲 EMI Suppression Components – Snubber networks and input/output filtering to minimize electromagnetic interference
