Autotransformer
With the autotransformer, the necessary rated voltage of 230 V AC can be generated in a three-phase 3-wire network without neutral conductor.
In most cases, 2 autotransformers are needed; for more information, see the section titled Network types. The use of a dual power supply is recommended in addition for 3KC3 transfer switching equipment.
