  • Fault current limiter for energy storage systems
    Patent number: 11916375
    Abstract: A fault-current limiting device having an input voltage node configured to receive a first voltage signal from an energy source, such as a battery, and an input reference node configured to receive a reference signal from the energy source. The device further includes a first switch coupled between the input voltage node and an output voltage node and a second switch coupled between the input reference node and an output reference node. The device further includes a current sensor circuit coupled to the output voltage node and coupled respectively to the first switch and the second switch wherein the current sensor circuit is configured to open the first and second switches in response to sensing a current signal at the output voltage node that exceeds a threshold current (e.g., a transient fault current).
