Abstract
A power supplying apparatus includes a conversion device to convert direct current (DC) power from a battery set into alternating current (AC) power. A current transformer arrangement may generate a DC charging signal based on the AC power and provide the DC charging signal to the battery set. The current transformer may include a plurality of current transformers.
