Abstract
A low voltage DC-DC converter for a vehicle includes: a switching circuit including a plurality of capacitors and a plurality of switches and converting a high voltage output from a high voltage battery into an AC voltage; a transformer converting the AC voltage output from the switching circuit into a low voltage; a current sensor measuring a current value output from the transformer; and a controller comparing the current value measured by the current sensor with a reference value to determine whether a current mode is a continuous current mode or a discontinuous current mode, and controlling one of the plurality of switches to be turned on or off as the determination result.
