A magnetic integration double-ended converter with an integrated function of a transformer and an inductor includes an integrated magnetic member having a magnetic core with three magnetic columns having at least three windings (NP, NS1, NS2) and at least one energy storage air gap, where a primary winding (NP) and a first secondary winding (NS1) are both wound around a first magnetic column or are both wound around a second magnetic column and a third magnetic column, and a second secondary winding (NS2) is wound around the second magnetic column; an inverter circuit with double ends symmetrically working, acting on the primary winding (NP); and a group of synchronous rectifiers (SR1, SR2), gate electrode driving signals of which and gate electrode driving signals of a group of power switch diodes (S1, S2) of the inverter circuit with the double ends symmetrically working complement each other.
