Patents by Inventor Ramesh Govindarajan

Ramesh Govindarajan has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • DC balancer circuit with zero voltage switching
    Patent number: 11923786
    Abstract: Disclosed herein are systems and methods for operation of a switched capacitor converter (SCC). In some variations, the SCC includes a resonant circuit including an inductor. Aspects of the disclosure include methods for controlling the SCC switches to decrease switching losses associated with operating the converter and to increase efficiency of the SCC. According to some aspects, a control method is used to switch converter switches under zero-voltage conditions. According to some aspects, a control method is used to switch converter switches under zero-current conditions.
    Type: Grant

  • DC Balancer Circuit With ZVS
    Publication number: 20210203222
    Abstract: Disclosed herein are systems and/or methods for operation of a switched capacitor converter (SCC). The SCC may include a resonant circuit including an inductor. Aspects of the disclosure include methods for controlling the SCC switches (e.g., modulation methods) to decrease switching losses associated with operating the converter and to increase efficiency of the SCC. According to some aspects, a control method may be used to switch converter switches under zero-voltage conditions. According to some aspects, a control method may be used to switch converter switches under zero-current conditions.
