Abstract

A transformer for an electrical device. The conventional method of converting 3-phase power into DC power uses semi-conductor elements or rectifiers. This transformer converts the voltages of the 3-phase system to produce 12 single-phase AC voltages, which are rectified so that 3-phase power can be readily converted into DC power
