  • Patent number: 9812949
    Abstract: A converter system and inverter system are disclosed with individual real and reactive power control for each phase of a poly-phase system. The converter system includes a controller, bidirectional single-phase inverters with AC sides coupled to an AC line filter and DC sides connected in parallel to a link capacitor coupled to DC/DC converters. Each inverter handles a separate AC phase. The controller controls the inverters and DC/DC converters so the current amplitude of each AC phase is independent, and the phase difference of each AC phase is independent. The inverters can be galvanically isolated between the DC and AC sides. The inverters can be non-isolated inverters having line and neutral connectors coupled to an isolated transformer winding, and the output windings of the transformer can be wired in a Wye configuration. The inverters can have local controllers.

  • Patent number: 9223372
    Abstract: An energy management system and method connecting a load to multiple energy sources. The system includes a load connection, source connections for each energy source, a control unit and at least one energy management module having an inductor and four switches. The first source is in parallel with the load. The first switch couples the first source positive terminal to the first inductor end, second switch couples the first source negative terminal to the first inductor end, third switch couples the second source positive terminal to the second inductor end, and fourth switch couples the second source negative terminal to the second inductor end. The control unit controls the four switches of each module to transfer energy between the energy sources through the module inductor. The system can have more than two sources. Modes including one or two switch, synchronous or asynchronous, and buck or boost can be used.

  • Patent number: 8174972
    Abstract: A method is described including determining if a packet length parameter included in received data matches a first pre-determined value, determining if an address parameter included in received data matches an address of a receiving device, determining if a length parameter included in received data matches a second pre-determined value, determining if a packet destination port number parameter included in received data matches a third pre-determined value, determining if a packet payload type parameter included in received data matches a fourth pre-determined value and dropping the packet responsive to the matches.
