Parallel operation of single phase inverter modules with no control interconnections
Abstract
To provide reliable power under scheduled and unscheduled outages requires an uninterruptible power supply (UPS) which can be easily expanded to meet the needs of a growing demand. A system suck as this should also be fault tolerant and include the capability for redundancy. These goals can be met by paralleling together smaller inverters if a control scheme can be designed to allow them to operate independently yet still share the load. We have developed a control technique for operating two or more single phase inverter modules in parallel with no auxiliary interconnections. This technique uses frequency, fundamental voltage, and harmonic voltage droop to allow independent inverters to share the load in proportion to their capacities. Simulation results are provided to prove the concept.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
