Abstract
A coupling node for regulating the current flow between two or more drives is described. The coupling node may include an interconnect circuit in communication with the drives for selectively opening the connection between the drives. A sensor circuit in communication with the drives measures one or more electrical properties of the drives or between the drives. A sensor circuit actuates the interconnect circuit in response to the measured electrical property of the two or more drives meeting predetermined criteria. In operation, when an electrical property of the drives, such as the current flowing between the drives, meets a predetermined criteria, such as an short circuit or current overload, as indicated by the sensor circuit, the controller actuates the interconnect circuit to open the connection between the drives.
