Abstract
A system includes a break-before-make automatic transfer switch (ATS) configured to selectively couple a utility grid and at least one distributed generator (e.g., a plurality of paralleled generators) to a load bus such that, in a state transition of the ATS, the utility grid and the at least one distributed generator are both disconnected from the load bus before the utility grid or the at least one distributed generator is connected to the load bus. The system further includes at least one converter configured to be coupled to the load bus and configured to provide power to the load bus during the state transition of the ATS.
