Title
(EN) FOUR-WAY AUTOMATIC TRANSFER SWITCH POWER TOPOLOGY
Abstract
(EN)

Systems and apparatuses include a mesh network for power distribution. The mesh network includes a plurality of interconnected four-way automatic transfer switches. Each four-way automatic transfer switch includes a common pole, a first pole selectively coupled to the common pole with a first switching device, a second pole selectively coupled to the common pole with a second switching device, a third pole selectively coupled to the common pole with a third switching device, and a fourth pole selectively coupled to the common pole with a fourth switching device. The common pole of a first interconnected four-way automatic transfer switch of the plurality of interconnected four-way automatic transfer switches is structured to provide power to a corresponding load, and the common poles of two or more of the plurality of interconnected four-way automatic transfer switches are structured to receive power from corresponding power sources.
