A method and a system sense at least one phase difference between at least two phases of a group of parallel connected three phase AC output terminals (e.g., a first phase AC output terminal, a second phase AC output terminal, or a third phase AC output terminal). The parallel connected AC output terminals may be three parallel connected DC to AC three phase inverters. Features of the parallel connected three phase AC output terminals enable wiring of conductors to one phase of an AC output terminal to be swapped with wiring of conductors of one phase of another phase AC output terminal. A sign of at least one phase difference is verified different from signs of other phase differences thereby the system determining the lateral position of the at least one three phase inverters relative to at least one other of the three phase inverters.

Providing positional awareness information and increasing power quality of parallel connected inverters

An apparatus for a system power device utilized in an interconnected power system. The interconnected power system may include multiple system power devices connected to various inter connections of groups of direct currents (DC) from power sources which also may be connected in various series, parallel, series parallel and parallel series combinations for example. The apparatus may include a processor connected to a memory and a communication interface operatively attached to the processor. The communication interface may be adapted to connect to a mobile computing system of a user in close proximity to the system power devices. A graphical user interface (GUI) of the mobile computing system may allow various operational and re-configuration options for the interconnected power system which may include installation, maintenance and monitoring schedules in the interconnected power system when the user of the GUI is in close proximity to the system power devices.

Circuit for a power device and graphical user interface

A power conversion system includes a first converter configured to convert an input voltage into discrete voltage levels, and provide each discrete voltage level at a corresponding output terminal. The power conversion system further includes a second converter configured to convert the discrete voltages into modulated voltages. The power conversion system further includes a selection unit configured to alternatively output each of the modulated voltage voltages across a pair of output terminals.

Multilevel converter circuit and method with discrete voltage levels

A power conversion system including a first converter configured to convert an input voltage into a plurality of discrete voltages. A second converter configured to convert the plurality of discrete voltages into a plurality of modulated voltages. Each modulated voltage of the plurality of modulated voltages comprises two voltage levels equal, respectively, to two of the discrete voltages of the plurality of discrete voltages. A selection unit configured to alternatively output each modulated voltage of the plurality of modulated voltages across a pair of output terminals.
