Abstract
An apparatus and a method are provided for controlling a low DC-DC converter (LDC) in an electric vehicle by prioritizing respective controllers, connecting the controllers in series in ascending order according to priority, and determining a command voltage of the LDC on the basis of output voltages of the respective controllers. Accordingly, even when a controller with a highest priority is operating, controllers of lower priority continue operating. Thus, electrical load performance degradation caused by instantaneous overcurrent generated in state transitions is prevented.
