Title:
TRANSFORMER FOR RECTIFIER
Document Type and Number:
Japanese Patent JPS5998510
Kind Code:
A
Abstract:
A rectifier transformer circuit permitting six-phase double-wye operation with 120 DEG conduction, (without the use of an interphase transformer), and providing any predetermined degree of phase shift. The transformer comprises a zig-zag wye primary winding and a six-phase star secondary winding. By choosing the proper ratio for the turns of the zig and zag portions of the primary winding, any degree of phase shift can be obtained. The rectifier transformer is ideally suited for multiple-phase installations wherein several rectifier transformers are used, each providing a different amount of phase shift, without the use of separate phase-shift transformers.
