  • System, method, and computer program product for a switch mode current balancing rail merge circuit
    Patent number: 9667068
    Abstract: A system, method, and computer program product are provided for merging two or more supply rails into a merged supply rail. The method comprises receiving two or more current measurement signals associated with two or more supply rails, selecting one supply rail from the two or more supply rails, based on the current measurement signals, and enabling the selected supply rail to source current into a merged supply rail.
    Type: Grant

  • Input rail dynamic power balancing and merging
    Patent number: 9570907
    Abstract: A dynamic multiple input rail switching unit includes a plurality of DC input voltage rails and a rail switching section coupled to the plurality of DC input voltage rails that is configured to individually connect selected ones of the plurality of DC input voltage rails to a switched rail output. The dynamic multiple input rail switching unit also includes a rail selection section that is coupled to the rail switching section and configured to dynamically choose the selected ones by balancing rail supply currents from the plurality of DC input voltage rails based on rail supply current capacity margins and a switched rail output current. A dynamic multiple input rail switching unit operating method, and a dynamic multiple input rail power converter are also provided.
