An arrangement for exchanging power with a three-phase electric power network includes a Voltage Source Converter having three phase legs with each a series connection of switching cells. A plurality of receptacles are mounted in raceways located in the panels with each receptacle including a housing and a plurality of conductors extending from one end of the housing to the other end of the housing. The first computing device may further identify a second device determined to be physically proximate to the first computing device, and may send an outgoing communication, based at least on the received incoming communication, to the identified second device. Disclosed methods and materials can prove highly valuable in many technological applications including, for instance, in formation of heat management materials for protective clothing and as may be useful in space exploration or in others that require efficient yet light-weight and flexible thermal management solutions.
