Product Features

High-power, low-harmonic and reliable power conversion for heavy-duty EV charging systems and industrial electric vehicle applications.

MW-Class Charging Capacity

Designed for high-power EV charging and battery swap stations, supporting 2.4MW–3.0MW charging systems with direct connection to 10kV/35kV medium voltage grids.

1200A Ultra-Fast Charging

Supports 720V DC bus systems and up to 1200A charging current, enabling ultra-fast charging for heavy-duty electric trucks and commercial vehicles.

Phase-Shifting Transformer Technology

Integrates phase-shifting transformer technology with 12-pulse or 24-pulse rectification to provide stable DC power output and improve charging system performance.

Low Harmonic Power Quality

Advanced phase-shifting design reduces grid harmonic distortion, achieving THDi ≤5% and power factor ≥0.95, minimizing the need for additional harmonic compensation.

10kV/35kV Medium Voltage Connection

Directly connects to 10kV/35kV power grids, replacing traditional step-down transformer plus low-voltage rectifier structures to reduce system complexity and losses.

Customized Charging Solution

Supports flexible configurations for charging capacity, voltage levels, DC bus systems, and battery swap applications to meet different heavy-duty EV requirements.
