Apparatus for controlling the voltage supplied to a load, comprising: a m ulti-phase transformer having a primary and a secondary winding for each pha se, each secondary being connected in series between an input line and an ou tput directed to the load; and the primary is configurable by switches such that the phase of the voltage of the secondary is different from the line to which it is connected by a phase different from 0 and 180 degrees. |
