The invention relates to an on-board system and a method for converting medium-voltage electrical power for a movable transport vehicle (10), comprising a plurality of conversion blocks (38.i) each having an upstream AC-DC stage (34) and an isolated downstream DC-DC stage (36), of the type in which, for each conversion block (38.i), the isolated downstream DC-DC power conversion stage (36) comprises a primary DC-AC converter (36A) produced in the form of a full bridge of controlled electronic switches and a transformer (36B) having a primary winding (36B1), connected to the downstream side of the primary converter and a secondary winding; characterised in that, for each conversion block (38.i), the primary DC-AC converter (36A) comprises a capacitive circuit (56) electronically inserted between an intermediate point (54) of the primary winding of the transformer (36B) and one side (48, 50) of the full bridge of the primary DC-AC converter (36A).
