The present invention belongs to the power source technical field and relates to a DC/DC conversion module. The DC/DC conversion module includes N sets of conversion units and a magnetic pole, wherein N is a positive integer greater than 1; each conversion unit comprises a voltage dividing unit, a first switch unit, a second switch unit, a first resonant capacitor, a first resonant inductor, a first transformer and a rectification unit; the voltage dividing units in the N sets of conversion units are connected in series; the voltage dividing units in the N sets of conversion units are used for performing equal voltage division on inputted direct current; the first resonant inductors in the N sets of conversion units are wound on the magnetic pole in a coupled manner; the frequencies of the first resonant inductors in the N sets of conversion units are the same; and the windings of the first resonant inductors in the N sets of conversion units have the number of turns; after the N inductors are coupled together, a forced current equalizing function can be realized, so that the voltage of each input capacitor is balanced.
