Innovation-Powered Next-Gen Power Conversion

HVLV DC-DC Converter

An HVLV DC‑DC converter is a power conversion device that steps down the high voltage of an EV traction battery to the low voltage required by the auxiliary battery.

We employ PCB‑winding‑based integrated planar magnetics that combine the transformer and inductors, dramatically reducing volume and material cost while simplifying manufacturing processes to improve mass‑production capability.

Leveraging our patented technology, the HV (800 V)‑MV (48 V)‑LV (12 V) three‑port bidirectional DC‑DC converter employs a single‑stage architecture across all ports, reducing material costs while delivering high power density.

Main Features

Integrated planar magnetic technology with PCB winding cuts material costs by 20%, reduces volume by 18%, and lowers losses by 26%.

Eliminating the high-voltage side circuitry in HVLV reduces volume by over 35% and cost by over 45%.

One‑PCB architecture supports SMT assembly and improves manufacturability.
