  • Scalable universal power supply and power converter
    Patent number: 9728965
    Abstract: A scalable universal power supply and/or power converter provides independent voltage, frequency, phase, and current control through a common power bus connected to a plurality of electrical conversion modules which can provide voltage, frequency, phase, and current control. According to one embodiment, a power supply and/or power converter includes a power bus; a plurality of terminals for input and/or output of electricity; a plurality of electrical conversion modules connected in parallel to the bus for transferring or converting electricity; a switch matrix, formed of a plurality of switches arranged in an array, connecting to the plurality of electrical conversion modules and the plurality of terminals; and a controller configured to select and operate one or more electrical conversion modules and one or more switches of the switch matrix to selectively provide and/or receive electricity to the one or more terminals.
