PROBLEM TO BE SOLVED: To provide a single-phase full-wave rectifying DC-DC converter of diode/choke coil direct connection system, which ensures easier connection between a cathode terminal of a diode and a bus bar forming a choke coil, and can reduce resistance loss and heat generation of the bus bar forming the choke coil. SOLUTION: The cathode terminals 410, 420, 430, 440 of diodes 41 to 44 of the DC-DC converter are allocated with displacement in the longitudinal direction of a lead-out terminal 50 of a choke coil 5 for smoothing a current which is composed of a bus bar.
