Embodiment Construction
[0020] The accompanying drawings disclose several specific embodiments of the present invention without limitation, and the present invention will be further described as follows in conjunction with the accompanying drawings.
[0021] Embodiment 1 of the present invention, with reference to appended figure 1 , is a schematic diagram of a central reverse coupling transformer. The transformer winding of branch 3 is split into n-1 parts, and n-1 reverse coupling transformers are formed with the remaining n-1 phase branches. "*" is the same name of the two-phase winding of the same reverse coupling transformer end.
[0022] Embodiment 2 of the present invention, with reference to appended figure 2 , is a schematic diagram of the end-to-end closed reverse coupling transformer. Each phase winding is divided into two windings connected in series, and the adjacent two-phase windings form a reverse coupling transformer, which are combined in turn to form a closed-loop connection.
