Title: Method and apparatus for minimizing magnetizing current of transformer
Inventor: ARUFU GUSUTAFUSON
IPC: H01F27/42
Filed: 1986-05-21
Abstract: The invention relates to a method and to an arrangement for controlling the respective conduction times of two directionally opposed electrical devices (9, 10) which are mutually connected in parallel and permit current to pass therethrough solely in one direction, and which also permit current (l<sub>2</sub>) to pass through the primary winding (2) of a transformer during a respective half-period of an A.C. voltage (U,) applied to the primary winding, this control being effected so that the magnetizing current through the transformer can be advantageously minimized and/or held beneath a given limit value when an asymmetric load (4, 5) is applied to the secondary side (3) of the transformer. A magnetizing current in the primary winding corresponding to the load (5) of the secondary winding (3) is controlled through the agency of different conduction times of the two directionally opposed devices (9, 10).

Title: Linked system
Inventor: IWAMI EIJI
IPC: H02M7/48
Filed: 1999-04-23
Abstract: PROBLEM TO BE SOLVED: To calculate the maximum voltage rise and eliminate setting by estimating a voltage for the neutral line of each power lines at the wire drop pole at a desired time. SOLUTION: V1a, I1a, V1b, I1b at the time (a) and time (b) are detected (step 1). The conditions of time (a) and time (b) are that I1a and I1b are different, and the actual drop pole voltage Vura at the time (a) between one power line and neutral line is equal to the actual drop pole voltage Vurb at the time (b) between one power line and neutral line. Here, the former half is that I1a and I1b are different due to ON/OFF of the load connected to one power line or change of output of single-phase 2-wire inverter 2.  The latter half is that capacity of the commercial power system 3 is sufficiently larger than the capacity of the single phase 2-wire system inverter 2, and Vura and Vurb are equal under the condition that the influence on Vura and Vurb by difference of I1a and I1b is regligible because a load of the neighboring customers is connected between the one power line and neutral line.
