  • Active balancing modular circuits
    Patent number: 7599168
    Abstract: Provided are active balancing modules that control voltage imbalances between capacitors stacked in a series arrangement and methods for their manufacture. These modules are simple and inexpensive to manufacture, and versatile. They may be used alone or they may be combined together to form a multi-module active balancing circuitry for a plurality of capacitors stacked in a series arrangement. The modules may further be aligned in either a side-by-side topology or an overlapping topology.
    Type: Grant
    Filed: February 6, 2008
    Date of Patent: October 6, 2009
    Assignee: Cooper Technologies Company
    Inventors: Frank Anthony Doljack, Neal Schultz, Hundi P. Kamath, Jim Strain
