Abstract
An arrangement for transforming electrical power is disclosed. An embodiment of the arrangement includes conductors for electrically connecting to an input source of three phase electrical power. This embodiment of the arrangement also includes a transforming device electrically connected to the conductors. The transforming device includes circuitry for transforming the input source of three phase power into at least two output phases separated from one another by approximately 180 electrical degrees. The transforming device also includes circuitry for reducing the level of instantaneous power drawn from the input source by shifting each output phase a predetermined number of electrical degrees from one of the three phases of the input source.
