A voltage balancing device is to be used in a dc power supplying system which includes first and second power supplying units that are connected in series to supply power concurrently operate an electrical load. The first power supplying unit has a negative terminal and a positive terminal to be connected to the electrical load. The second power supplying unit has a positive terminal connected to the negative terminal of the first power supplying unit, and a negative terminal to be connected to a ground. The voltage balancing device includes a reference voltage generating unit connected in parallel to the power supplying system and having an output that provides a reference voltage, and a comparator unit having a first input port connected to the output of the reference voltage generating unit, a second input port connected to a junction of the first and second power supplying units of the power supplying system so as to receive a detected voltage therefrom, and an output port connected to the second input port.
