Bhaskaran R. Nair 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).

  • High efficiency voltage mode class D topology
    Patent number: 10230341
    Abstract: A high efficiency voltage mode class D amplifier and energy transfer system is provided. The amplifier and system includes a pair of transistors connected in series between a voltage source and a ground connection. Further, a ramp current tank circuit is coupled in parallel with one of the pair of transistors and a resonant tuned load circuit is coupled to the ramp current tank circuit. The ramp current tank circuit can include an inductor that absorbs an output capacitance COSS of the pair of transistors and a capacitor the provides DC blocking.
    Type: Grant
    Filed: January 8, 2018
    Date of Patent: March 12, 2019
    Assignee: Efficient Power Conversion Corporation
    Inventors: Michael A. de Rooij, Johan T. Strydom, Bhaskaran R. Nair
