(H)EV - Auxiliary HV/LV DC/DC

The architecture of electric vechicles comprises at least one low-voltage sub-network with a low-voltage energy storage and multiple electrical loads, and one high-voltage sub-network with a high-voltage energy storage. The auxiliary HV/LV DC/DC job is to enable the bi-directional energy flow between these two electrical subnets.

Your biggest challenges: achieving greatest-possible efficiency and keeping overall system costs in check. The space required for the DC/DC should also be kept to an absolute minimum. Infineon’s portfolio is specially designed to help you overcome these barriers with ease.
