Notes
Why it is interesting: a modular 11 kW building block intended to be paralleled into 30–150 kW chargers, with 1700 V CoolSiC on one side. It comes with firmware and a GUI.
Watch out: hardware is “not for sale yet” (board available on application). The input-voltage range is not stated on the product page; read it from the user guide before comparing against the TI and Wolfspeed DAB/CLLC entries.
