What it does and how

Applications

APP

High-power EV fast-charging stations (120 kW) with bidirectional power transfer and grid ancillary services such as peak-shaving and grid stabilisation
Mobile off-board chargers supplying loads from a battery, e.g. vehicle-to-home (V2H) backup or camping power

Technologies

TECH

Integrated magnetics: the inductor is built into the transformer, reducing part count and raising power density
Ripple-free charge current that meets the CHAdeMO 2.0 (2018) standard
Novel SDM/SDMM modulation enabling soft switching across the full power range with improved high-frequency output ripple

Benefits
