Abstract: DC power systems operating at 48 V and higher may increase risk for sustained electrical arcs. In particular, a series arc may be formed and sustained when a connection fails open between a power source and an electrical load that continues to operate while the arc is present. In some applications, many or all modules may already be interconnected via network links, such as a Controller Area Network (CAN) bus, a Local Interconnect Network (LIN) bus, Ethernet, and so on. An arc detection and mitigation system may leverage an existing communication network to enable arc detection and mitigation while avoiding excessive additive costs.
