  • Patent number: 11152792
    Abstract: A method is disclosed for controlling the operating of a consumption appliance by way of a selector switch controlled by an energy saving device connected to a management center. The consumption appliance is kept in its default power mode, until receiving, by the energy saving device, an authentic secured control message sent by the management center. This message includes a command onto the mode in which the consumption appliance has to be switched. A counter is initialized with an initialization value before to be triggered. The consumption appliance is switched in the mode indicated by the command, either until the counter has reached a threshold value, or until receiving another authentic control message. If the counter has reached the threshold value, then the consumption appliance is switched in its default power mode. If another authentic secured control message has been received, then returning to the step of initializing the counter.

  • Patent number: 10938212
    Abstract: The device includes an electric energy source to which an inverter is power-connected, whose output is three-phase with symmetrical power distribution. It further includes an inter-phase power transfer module which is power-connected to the inverter and comprises at least one first power board including at least three power transistors. The inter-phase power transfer module has a data interface and has a first output with asymmetrical power distribution into three phases, wherein the first output is further connected to a distinctive nodal point, this distinctive nodal point being power-connected to a load. Through a measuring module, the PLC control system is also connected to the distinctive nodal point, the PLC control system being further connected also to the inverter and the data interface. This arrangement ensures that the power supplied to the load reflects in each phase the power consumed by the load.
