Last update: 05 Sep. 2023

What is a High Voltage DC/DC converter?

The High Voltage DC/DC converter is a reversible electronic device which lowers the Direct Current from the High Voltage battery to a Low Voltage Direct Current used by most of the vehicle electrical equipment (e.g. dashboard, electric window…). The DC/DC converter is also in charge of keeping the passengers safe by insulating them from the High Voltage electricity network.
