Technical Specifications Rated Blocking Voltage: 3500V Gate Signal Interface: Fiber‑optic Cooling Structure: Double‑sided press‑pack water‑cooled Operating Junction Temperature: -40℃ to +150℃ Storage Temperature: -40℃ to +85℃ Relative Humidity: 5%‑95%, non‑condensing Cooling Water Flow Requirement: 12‑16L/min Vibration Compliance: IEC 60068‑2‑6 Mean Time Between Failures: Exceeds 200000 hours Net Weight: 11kg
Functional Features Supports high‑speed turn‑on and forced turn‑off of high‑power power loop. Provides snubberless operation to remove requirement for external absorption circuit. Delivers low on‑state conduction loss to reduce system heat generation. Implements optical fiber gate drive to achieve complete galvanic isolation between control circuit and high‑power main circuit. Supports series‑parallel assembly for higher‑power system construction.
Application Scenarios
Core component in medium-voltage frequency converters for mining conveyors, metallurgical rolling mills, and large pumps. Deployed in static VAR compensators (SVC), active power filters (APF), and FACTS devices for grid stability. Used in large wind turbine converters, solar PV inverters, railway traction converters, and marine propulsion systems.
Installation and Usage Notes
Install the module into the converter power stack observing the specified clamping force against a flat, clean heat sink. Ensure proper cooling interface preparation before applying DC-link voltage. Connect the gate drive interface according to the manufacturer’s wiring diagram. Verify all protective functions are correctly configured in the converter control system. Perform a controlled startup with gradual voltage ramp-up while monitoring gate driver feedback.
