<p>PURPOSE:To reduce a voltage drop and an eddy current loss by improving utilization rate of a primary winding provided on a core leg of a two-leg core and reducing a magnetic flux and an inductance generated due to a commutating current. CONSTITUTION:Secondary windings of core legs are formed of divided windings 531, 532, 541, 542. Rectifiers 61, 63 and 62, 64 are so connected that currents flowing to the windings 513, 541 and 532, 542 become reverse to constitute transformer rectifiers independent for the legs so that AC currents flow to primary windings of the respective legs. A combination of terminals in which communicating currents simultaneously flow reversely of terminals u1, x1, y1, v1, u2, x2, y2, v2 are set to one, directly opposed to be extended thereby to reduce magnetic flux and commutating inductance to be generated.</p> |
