Technical Specifications IGBT rated voltage 1200 V, rated current 300 A. Gate driver working power supplied by converter auxiliary power. Supports high‑frequency pulse switching. Operating temperature 0 ℃ to +80 ℃, storage temperature ‑40 ℃ to +85 ℃, non‑condensing relative humidity 5%‑95%. Built‑in short‑circuit and over‑current hardware protection for power chip.
Functional Features Gate driver board amplifies control pulse signals and drives IGBT chip on‑off operation. Realizes high‑power AC‑DC‑AC power conversion for frequency converter. Collects power unit fault signals and feeds back fault status to main control system. Monitors IGBT desaturation state for short‑circuit protection. On‑board test points support maintenance inspection.
Application Scenarios Power unit spare part for ABB high‑power industrial drive equipment. Widely used in metallurgy, mining, large‑size water pump and fan frequency converter maintenance projects.
Performance Parameters High‑current high‑voltage switching performance. Fast short‑circuit protection response. Stable continuous high‑power operation capability.
Material Composition IGBT power module metal baseplate with silicon power chip. Ceramic insulation layer inside power module. Multilayer glass‑fiber epoxy printed circuit board for gate driver. High‑power copper busbar terminals, signal connectors and metal fixing hardware. Thermal interface conductive silicone pad.
Structural Characteristics Combined assembly structure of power module and gate driver board. High‑power bus terminals on power module side, low‑voltage signal connectors on driver board side. Mounting holes for screw fastening onto radiator surface.
Working Principle Driver circuit amplifies pulse voltage to drive IGBT gate pole, IGBT chip completes high‑voltage main‑circuit switching. When short‑circuit fault occurs, desaturation detection circuit triggers rapid turn‑off protection and sends fault feedback signal to main control unit.
Installation Requirements Apply uniform thermal conductive silicone grease between IGBT baseplate and radiator. Fasten whole assembly onto radiator with specified torque.
Usage Notes Strictly implement anti‑static protection for power chip and driver board. Ensure sufficient torque for radiator mounting screws to guarantee thermal contact.
