摘要： PURPOSE:To decrease stray loss caused by leakage flux and obtain a highly efficient stationary electromagnetic induction apparatus by constituting a single turn planar coil of a plurality of coil elements wound in parallel. CONSTITUTION:Respective coil elements 12-14 which are located at external, central, and internal sides of a coil are connected in parallel by connecting conductors (no structure is shown in Fig.) consisting of respective lead parts 12a-14a and 12b-14b. Further, low voltage wiring is constructed so that 4 sheets of plate coils 11 are connected in parallel in the same manner as conventional examples. Consequently, leakage flux that is interlinked perpendicularly in the vicinity of both side peripheral parts of the conductors of plate coils 11 is so large that the conductor widths of the coil elements 12 and 14 located at the external and internal sides are made to be narrower than that of the central coil element 13 in consideration of the state of above leakage flux. This configuration decreases stray loss effectively.

摘要： PURPOSE:To simplify the composition of a circuit, by balancing the DC winding current of two sets of DC winding groups flowing on the primary side of an interphase reactor (IPR), with circulating current flowing to the secondary winding of the IPR. CONSTITUTION:So far as a rectifier 20 having a transformer 10a for the rectifier is concerned, at the time of commutation from a phase n to a y phase for example, on the sides of the primary windings 51a, 51b of an IPR 50, current burdening full-load current flows. In the meantime, on the sides of the secondary windings 52a, 52b of the phase u and phase y of the IPR 50, current corresponding with the ampere turn (AT) of the windings 51a, 51b flows as circulating current I2. In this case, when the load current of the IPR 50 of the phase u is made greater than that of the phase y, then on the side of the winding 52a of the IPR 50 of the phase u, more current increased by component corresponding with the AT flows. However, the winding 52a of the phase u is set in a state that it is series-connected to the winding 52b of the phase y, to compose a closed circuit, and so increased current flows also into the winding 52b of the phase y and works to increase the partial charge of load current. As a result, to the phase u and the phase y, the load current is to flow half by half.
