  • Device and process for detecting and mitigating reverse power-flow
    Patent number: 11329551
    Abstract: A power sensing and switching circuit, using voltage and current sensors, integrated circuits and logic gates that detects reverse power flow, from reactive loads, non-linear loads or dispersed electrical generators, and mitigates reverse power flow by functioning as a power factor correction device and by diverting the reverse power flow as recycled power to storage, local usage, or remote usage via a recovery line that mitigates distribution grid instability and speeds up the growth of dispersed electrical generators.
    Type: Grant
