  • Publication number: 20240297769
    Abstract: Systems for co-site interference mitigation are provided herein. A system according to an embodiment receives first spectrum usage data indicating parameters to be used by a first group of one or more radio elements to send or receive transmissions. The system receives second spectrum usage data indicating parameters to be used by a second group of one or more radio elements to send or receive transmissions. The system dynamically determines, based on the first and second spectrum usage data received in real time, that interference will occur between the first group and the second group. The system forwards, to the at least one of the radio elements, a signal indicating parameters for mitigating the interference between transmissions to be sent or received by the radio elements of the first or second group.

  • Publication number: 20240297577
    Abstract: A controller for a DC-AC inverter circuit. The circuit comprises two terminals for receiving a DC-link voltage, two or more capacitors connected in series between the two terminals, wherein each capacitor has a capacitor voltage. The circuit is configured to convert an input electrical power to an output electrical power for operating a main electrical load. The controller is configured to, in response to the main electrical load becoming non-operational, configure the circuit into a balancing mode. In the balancing mode the controller configures the circuit to output electrical power to an electrical component, such that the DC-AC inverter circuit remains operational to balance the capacitor voltages while the main electrical load remains non-operational.
