Off-Board Charger Sub-Unit Power Converters

Littelfuse Off-Board Charger Sub-Unit Power Converters are required for DC charging stations capable of charging to 80% SOC in under 30 minutes. These fast-charging applications require modular power converters, which can be paralleled to cater to different power levels, thereby enabling fast charging. The most critical parameters are energy density and system efficiency. A sub-unit power converter in a DC charging station consists of an AC/DC power stage and DC/DC power stage integrated into the charging station.
