Abstract: An electric vehicle (EV) charging system includes a plurality of electrical vehicle supply equipment (EVSE) units, a plurality of associated EV charging stations, phase conductors coupled between the charging stations and corresponding bi-directional solid-state switches and a neutral conductor configured to complete charging circuits with associated ones of the phase conductors, and an EVSE communications bus. Each EVSE unit includes a microcontroller unit (MCU) and driver that control current flow through the bi-directional solid-state switches providing charging current to respective EV charging stations and connected plug-in EVs (PEVs). The MCUs communicate over the EVSE communications bus and, as PEVs plug into, charge, and unplug from the plurality of EV charging stations, reallocate or reapportion an available supply current among the plurality of EVSE units while also dynamically adjusting one or more circuit protection attributes provided by the EVSE units.

Abstract: In an electrical distribution system including a solid-state circuit breaker (SSCB) and one or more downstream mechanical circuit breakers (CBs), a solid-state switching device in the SSCB is repeatedly switched ON and OFF during a short circuit event, to reduce a root-mean-square (RMS) value of the short circuit current. The resulting pulsed short circuit current is regulated in a hysteresis control loop, to limit the RMS to a value low enough to prevent the SSCB from tripping prematurely but high enough to allow one of the downstream mechanical CBs to trip and isolate the short circuit. Pulsing is allowed to continue for a maximum short circuit pulsing time. Only if none of the downstream mechanical CBs is able to trip to isolate the short circuit within the maximum short circuit pulsing time is the SSCB allowed to trip.

Abstract: A dynamically coordinatable electrical distribution system includes a plurality of intelligently-controlled protection devices (PDs), a communication and control bus (comm/control) bus, and a central computer. The plurality of intelligently-controlled PDs is configured to protect a plurality of associated electrical loads from faults, developing faults, and other undesired electrical anomalies. Each of the PDs further has electrically adjustable time-current characteristics. The intelligently-controlled PDs are communicatively coupled to the comm/control bus and configured to report current data representative of real-time currents flowing through their respective loads to the central computer, via the comm/control bus. The central computer is configured to communicate with the plurality of PDs over the comm/control bus and dynamically coordinate the time-current characteristics of the plurality of PDs based on the current data it receives from the PDs.

Abstract: A solid-state circuit protector includes a first power semiconductor device having an ON resistance that increases with increasing temperature and a second power semiconductor device connected in parallel with the first power semiconductor device having an ON resistance that decreases with increasing temperature. During times when abnormally high currents are flowing through the solid-state circuit protector, the second power semiconductor is switched ON so that some or all of the current is diverted through it, thus protecting the first power semiconductor device from being damaged due to overheating. The first power semiconductor device is either switched OFF, allowing it to cool in anticipation of a lighter load, or is configured to remain ON so that it shares the burden of carrying the high current with the parallel-connected second power semiconductor device yet operates cooler and at a lower ON resistance since it is not required to pass the full current.

Abstract: A solid-state circuit breaker (SSCB) with galvanic isolation capability includes an electrical bus with line-side and load-side terminals and a solid-state device connected in series with a closeable air gap between the line-side and load-side terminals. During normal operating conditions, the solid-state device is switched ON and the SSCB forces movable contacts inside the SSCB to close the air gap, so that an electrical current path is maintained between the line-side and load-side terminals and electrical current is allowed to flow through the SSCB and an attached load. Upon a short circuit or overload of unacceptably long duration occurring in the load circuit, the SSCB switches the solid-state device OFF to prevent current from flowing through the load, and releases the movable contacts to open the air gap and thereby establish galvanic isolation between the line-side and load side terminals.
