Performance characteristics
High Power Density
The power density is raised by 30%, improving turbine design flexibility
Good Compatibility
Catering to market needs, the product supports the derivative integration with the master control unit and with the turbine auxiliary transformer
Standardization of Parts
Key components of the whole series of converters, such as grid-connected contactors and fans, are standardized to reduce parts categories
Optimized Heat Dissipation Design
The optimized heat dissipation layout inside the cabinet, together with external fans, enhances the converter's environmental adaptability
Higher Efficiency
The filter design is optimized to reduce the grid-side excitation current and the rotor's excitation current, thereby lowering converter losses
Remote Monitoring and Intelligent Diagnosis
The remote network system of the converter can intelligently diagnose wind turbine faults
