WebCCM PFC mode. There are also Level 3 EVSEs that consists of an external charger supplying high voltage 300 to 750 VDC up to 400 A to the automobile. For these power levels a digital based system is preferred still requiring a PFC where the PFC is typically a Vienna Rectifier. [3] Digital based systems may also be preferred in Level 2 systems. [4]
