摘要
The system of the dc / dc conversion of the modular electrical energy (2) comprises a primary converter rectifier (10) having a structure of the asymmetrical bridge with two electronic switches (24, 32) which is supplied under a dc voltage between a first supply terminal (6) and a second supply terminal, and which supplies between two intermediate terminals (30, 36) of the electrical energy to at least two modules of the stator (12, 14, 16). Each conversion module (12, 14, 16) is supplied by the primary converter (10) through a transformer associated with different (40, 42, 44) having a single primary winding (50, 52, 54). At least the total number n least one of the converter modules (14, 16) comprises respectively a first isolation diode of magnetization (182, 184) connected in series with the primary winding (52, 54) being biased by conduction to the second intermediate terminal (36), and a second isolation diode of the demagnetization (192, 194), or on the primary winding (52) of the associated transformer, or on a secondary winding of transformer associated taken from the at least one winding of the useful load or a secondary winding additional dedicated solely to the demagnetization.
