CTS1070 series integrated AC-DC module delivers 6.6kW bidirectional power conversion for 800V EV platforms. Supports charging and inverter (V2G/V2L), with up to 8 units parallel for scalable high-power systems.
The CTS1070 is a high-power bidirectional power conversion module designed for modern 800V EV architectures. In charging mode, it converts grid AC to DC for battery charging. In inverter mode, it feeds battery DC back to AC — enabling V2G, V2L, and emergency backup power.
Up to 8 identical units can operate in parallel without a master controller, scaling from 6.6kW up to 52.8kW in the same compact form factor.
The CTS1070 series is an integrated 6.6kW bidirectional on-board charger module built on a fully digital soft-switching control platform. Designed for passenger vehicles, logistics fleets, and high-voltage industrial applications.
Built on a fully digital soft-switching control architecture, the module achieves high efficiency across the full load range while maintaining low electromagnetic interference.
Bootloader support and background debugging allow firmware updates and parameter tuning in the field — no hardware modification required.
