Custom Dry-type Transformers for Heavy-Duty EV Charging Transformer
Custom Dry-type Transformers for Power Distribution Applications
Our Approach
We design phase-shifting rectifier transformers based on high-voltage direct connection and multi-pulse rectification architecture, enabling efficient and grid-friendly megawatt-level power conversion.
Our focus is on:
• High-efficiency high-voltage (10kV/35kV) direct grid connection
• 12-pulse / 24-pulse rectification for low harmonic distortion
• Stable DC output for megawatt fast charging systems
• High power factor operation with minimal reactive power impact
• Compact, integrated design for reduced footprint and simplified system layout
Engineered for stable, efficient, and grid-friendly power conversion in modern heavy-duty truck charging and battery swap applications.
What We Deliver
• Metro and subway substations
• Rail transit auxiliary power systems (stations, tunnels, depots)
• Traction-related power distribution systems
• Custom engineered solutions for urban rail infrastructure power systems
