Voltage-boosting/lowering DC/DC converter includes a low-voltage-side port and high-voltage-side port, an inductor connected at one end to a positive-pole terminal of the low-voltage-side port, and a transformer of a magnetic-field cancellation type including a primary winding and secondary winding interconnected in an oppositely-wound configuration, a common terminal of the primary winding and secondary winding being connected to the end of the inductor. Switching element controls an energizing current of the primary winding flowing to a common reference terminal, another switching element controls an energizing current of the primary winding flowing to a positive-pole terminal of the high-voltage-side port, still another switching controls an energizing current of the secondary winding flowing to the common reference terminal, and still another switching element controls an energizing current of the secondary winding flowing to the positive-pole terminal of the high-voltage-side port.
