CPC H02M 7/003 (2013.01) [H02J 3/38 (2013.01); H02J 7/0042 (2013.01)] | 29 Claims |
1. A framework for a multi-phase energy system comprising:
a plurality of modules arranged in a plurality of cabinets, wherein each module comprises an energy source configured to output a DC voltage, a converter coupled with the energy source, and a local control device configured to control the converter to output a module voltage of +DC volts, zero volts, or −DC volts; and
a master control device communicatively coupled with the local control devices of the plurality of modules, the master control device configured to provide control information to the local control devices of the plurality of modules,
wherein the local control device of each module is configured to control the module voltage output by the module based on the control information from the master control device,
wherein the plurality of modules are connected as a plurality of arrays such that each array is configured to output an AC signal having a different phase angle, wherein the modules within each array are connected as levels of that array such that the AC signal output by that array is a superposition of the output voltages from each module of that array,
wherein each cabinet holds the modules belonging to at least one same level of the plurality of arrays stacked along an axis orthogonal to a reference plane such that the modules of the at least one same level are aligned along the axis, and
wherein, for at least two adjacent levels of the arrays, modules are stacked in order of array such that modules of the same array are aligned parallel to the reference plane at a same common distance from the reference plane.
