Actually, most of them boost 120 and 240 to the same high DC voltage (300-400v) using a power-factor-correction (PFC) circuit, probably similar to what's in the Leaf's charging system. The relatively fixed high DC voltage is then converted to low voltage DC.drees said:..I know that even regular computer power supplies are very often at least a couple percent more efficient when running on 220 vs 120 and they are only converting AC to low voltage DC.
I2R Losses in the PFC circuit are reduced at higher input voltages (240v).
Charger operates between 260-400V and change, DC
