Abstract
To provide a DC/DC converter capable of down-sizing magnetic components and varying boosting and bucking ratios, and a bidirectional boosting-bucking operations, a bidirectional boosting-bucking magnetic-field cancellation type of DC/DC converter (10) is provided which includes: a first voltage side port (P1), a second voltage side port (P2); a common reference terminal (CP), a smoothing capacitor (C1), four switching elements (SW1, SW2, SW3, SW4), an inductors (L1, L2), a magnetic-field cancellation type transformer T including a primary winding (L3) and a secondary winging (L4), four switching elements (SW5, SW6, SW7, SW8), and a smoothing capacitor (C2).
