  • Modular uninterruptible power supply apparatus and methods of operating same
    Patent number: 10568232
    Abstract: An uninterruptible power supply system includes a plurality of functional modules interconnected to form a power distribution network coupling at least two power sources to a load. Each functional module has at least two ports coupled to at least one other of the functional modules and/or to at least one other external device and includes a control circuit configured to autonomously control at least one function relating to electrical power transfer between the at least two ports. The system further includes a controller module configured to communicate with each of the functional modules over at least one digital communication link to control power flow between the at least two power sources and the load.
    Type: Grant
    Filed: September 15, 2017
    Date of Patent: February 18, 2020
    Assignee: Eaton Intelligent Power Limited
