Abstract:
A fan, characterized in that the conversion device (59) is made up of three separate single-phase autotransformers (79a, 79b, 79c) that are magnetically uncoupled, each single-phase autotransformer (79a, 79b, 79c) being connected to one of the input terminals (70a, 70b, 70c) and at least one of the output terminals (71a1, . . . , 71c1, 71a2, . . . , 71c2), and being able to modify the voltage values of a single-phase input AC current coming from the corresponding input terminal to obtain a modified output current on the or each output terminal (71a1, . . . , 71c1, 71a2, . . . , 71c2) corresponding to that single-phase autotransformer (79a, 79b, 79c).
Abstract:
The invention relates to a cooling assembly (15) including: a conduit (16) including a side wall (17) and a fan (20) comprising: a rotating electric machine (32) a power supply module (35) including: three distinct single-phase self-transformers (79a, 79b, 79c) and magnetically decoupled, each self-transformer (79a, 79b, 79c) surrounding the side wall (17) of the conduit (16).
