SUPPLY CHAIN INCLUDING A SUPPLY DEVICE FOR POWERING AN AC OR DC APPLICATION LOAD FROM AN AC ELECTRICAL SUPPLY NETWORK

摘要

Supply chain comprising a supply device and a load (25), the supply device comprising: an autotransformer (21) exhibiting at output N (integer 2) triplets of distinct phases, N rectifiers (22) each linked at input to a triplet of phases and exhibiting at output a pair of polarized terminals (+, -), an application converter stage with DC input and AC or DC output (24, 24') linked at input to the rectifiers (22) by way of a filtering stage (23) and at output to the load (25). The application converter stage (24, 24') comprises N application converters with DC input and AC or DC output (24.1, 24.1') and the filtering stage (23) comprises N filtering circuits (23.1), each of the application converters (24.1, 24.1') being linked at input to one of the filtering circuits (23.1), this filtering circuit (23.1) being linked directly at input to the pair of polarized terminals (+, -) of one of the rectifiers (22), each of the application converters (24.1, 24.1') linked at output to said load (25).
