• Control/Drive Circuit: Includes gate drive, protection circuit, etc.

Typical Application Fields

• HVDC converter valves for high-voltage direct current transmission.
• High-power traction drives (railways, rail transit).
• Wind power, photovoltaic inverters, and other renewable energy systems.
• Industrial motor drives and frequency converters.
• Electric vehicle charging and discharging stations and power systems.
• High-voltage power distribution and power system protection devices.

Installation and Maintenance Guidelines

• On-site Inspection: Verify that cabinet space, heat dissipation conditions, and power supply matching meet specifications.
• Mechanical Fixing: Secure the module to reserved mounting holes with bolts to ensure reliability against vibration and impact.
• Electrical Wiring: Use copper bars or high-voltage cables that meet rated current requirements, strictly following phase sequence and grounding regulations.
• Heat Dissipation System: Select water-cooled or air-cooled solutions based on power density, and check the flow rate and temperature of the cooling medium.
• Commissioning and Testing: Conduct insulation resistance and ground continuity checks before power-on; verify gate drive waveforms, switching time, and power loss on-site after power-on.
• Maintenance: Regularly inspect heat sink surface cleanliness, replace cooling medium, and check terminal tightness; record operating parameters (temperature, load, current) for predictive maintenance.
• Safety: Wear insulating gloves during operation and comply with safety standards such as IEC 61850/IEC 60204.
