A system for improving resolution of a voltage command of a low voltage DC-DC converter is provided. The system includes a voltage command signal generator that generates a first voltage command signal having a magnitude of a first specific range for a first voltage command of the low voltage DC-DC converter and a scale part that varies the first voltage command signal generated by the voltage command signal generator based on a preset scale ratio. An offset part sets a minimum value of a variable range of the first voltage command signal of the low voltage DC-DC converter. A resolution increasing part reduces the variable range of the first voltage command signal of the low voltage DC-DC converter by adding an output of the scale part and an output of the offset part.
