Abstract: A resilient on-site microgrid system includes a multiport power router directly connected to various energy sources, including batteries, renewable energy sources, and broader grid power, as well as various loads, including electric vehicle chargers. The multiport power router dynamically adjusts power provided from the various power sources and to the various loads, especially to power devices in a nearby facility. The microgrid system includes various bypass systems allowing for powering of critical loads in the event of failure of individual components or pathways within the microgrid system.

Abstract: A modular, multiport power conversion system includes a central transformer with a plurality of windings inductively connected to the central transformer. The plurality of windings are connected to ports able to connect to both AC and DC-devices, including both power sources and power consuming nodes. Each port is able to be selectively galvanically isolated, such that a controller is able to determine from which ports power is drawn and/or to which ports power is transferred. The system is operable to use zero voltage switching (ZVS) and/or zero current switching (ZCS) for each port to reduce power loss and increase efficiency, especially for high frequency embodiments.

Abstract: A circuit breaker modular interconnect system includes a plurality of contactors attached to primary busbars. The primary busbars are configured to interlock with secondary busbars leading to terminals to which cables are able to attach. A connection module is fit around the interlock point between the primary busbars and the secondary busbars and then fixed in order to retain a strong connection between the primary and secondary busbars. The connection module is able to include a plurality of sections, lined with electrically conductive material and configured to surround the interlock points to assist in maintaining strong electrical connection between the primary and secondary busbars.

Abstract: A charge cable connection system includes male and female connectors. The male connector includes a plurality of spring-loaded pins including a central pin connected to an earth wire. The female connector includes a plurality of insertion points able to receive the pins of the male connector and rotate through radial slots until the insertion points align with openings such that the pins are able to be pushed forward by respective springs until they tightly connect corresponding pins of the female connector.
