Working Principle:
This module operates as a fully controllable switch in high-voltage converter topologies. The integrated gate extracts carriers from the entire cathode area simultaneously, enabling fast and uniform turn-off. The asymmetric design is optimized for converters with anti-parallel diodes or in applications where reverse blocking is not required.
Installation Requirements:
- Clamping Pressure: Apply precise, uniform pressure using calibrated hydraulic or mechanical presses.
- Cooling: Ensure adequate coolant flow and temperature control.
- Snubber Design: Implement snubber circuits rated for the high voltage and energy.
- Clearance: Maintain high-voltage creepage and clearance distances.
Usage Precautions:
- High Voltage Safety: Strictly adhere to high-voltage safety protocols during installation and maintenance.
- Pressure Uniformity: Use pressure-sensitive films to verify uniform clamping.
- Gate Power: Ensure gate power supply can deliver peak currents without droop.
- Storage: Store horizontally in original packaging to prevent mechanical stress.
