A DC-DC converter comprising: an n number of first serial circuits (CS11, CS12) comprising an inductor and a switching element; and a second serial circuit (CS2) having an n number of rectifying elements (D1, D2) connected in series so as to have the same rectification direction. When n = 2, one end of the second serial circuit (CS2) is connected to a connection point (P11) between an inductor (L1) and a switching element (Q1) in the first serial circuit (CS11) and the other end of the second serial circuit (CS2) is connected to a smoothing capacitor (Cout) and one end of a load (RL). A connection point (P12) between an inductor (L2) and a switching element (Q2) is connected to a connection point between the rectifying elements (D1, D2) via a capacitor (C2). The odd-number switching element (Q1) and the even number switching element (Q2), in order of connection to the second serial circuit (CS2), are complementarily driven. |
