Current sharing signal coupling/decoupling circuit for power converter systems

摘要: An improved current sharing signal coupling/decoupling circuit for power converter systems, including the provision of an individual each module a number parallel connected modules, providing interface between module's "current signal" port and common connection bus. The circuits also share ground noted in disclosure as ground". includes comparator, bi-directional switch variable voltage reference. comparator senses difference on bus, "common signal," less amount set by reference circuit, port, "module signal". If drops below signal, activates switch, disconnecting from allowing remaining modules to continue normal operation, thus system that is tolerant faults. n are minimum required meet system's output specification, then use n+1, n+2, . n+N with corresponding will allow continued operation event failure 1, 2, N reliability increasing excess n.
