<p>Three coils, each having several serial windings (A1-A4 or 5; B1-B4 or 5; C1-C4 or 5), have selected windings connected in a delta (A2-A4 or 5; B2-B4 or 5; C2-CR or 5). Input AC power is applied through outrigger windings (A1, B1, C1)at the delta apices (A, B, C). At least two strategically located, direct tap, natural output points (01-06; or 01, 02, 04, 05, 07, 08) are provided at each side of the delta. For 6-phase output, only the six natural output points (01-06) are required. For 9-phase output, an additional central output terminal (09, 06, 03) connects to each side of the delta through a stub winding (A6, B6, C6). The 6-phase or 9-phase output is passed to a rectifier circuit (R).</p> |
