ENDLESS CORE FOR A MULTIPHASE TRANSFORMER AND A TRANSFORMER INCORPORATING SAME

摘要

Endless core (10) for a multiphase transformer (12) is formed as an endless circular or annular loop. A plurality of windows (14) are formed through and about the core (10). Adjacent windows (14) share a common portion or leg (16). Thus magnetic flux is shared between windows (14). Transformer (12) is constructed by winding respective primary windings (18) and secondary windings (20) through the windows (14). The core (10) and transformer (12) allow for an infinite possibility of phase shifting or combining because portions of the second windings (20) can be wound through more than one of the windows (14).
