With￿the￿combo￿charging￿at￿7.4 kW￿AC￿charging￿power￿the￿convenience￿charging￿electronics￿can
convert￿both￿the￿single-phase￿AC￿voltage￿of￿the￿AC￿charging￿station￿to￿direct￿current￿voltage,￿and￿shift
through￿the￿direct￿current￿voltage￿of￿the￿DC￿charging￿station￿for￿the￿electrical￿machine￿electronics
and￿high-voltage￿battery￿using￿the￿DC￿switch￿contactors.￿The￿conversion￿of￿the￿AC￿voltage￿to￿the
direct￿current￿voltage￿required￿for￿charging￿the￿high-voltage￿battery￿is￿done￿by￿the￿AC/DC￿converter
at￿a￿maximum￿power￿of￿3.7 kW.￿The￿properties￿and￿function￿of￿the￿AC/DC￿converter￿were￿already
