Patents by Inventor Sandeep Taneja

Sandeep Taneja 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).

  • Patent number: 8830638
    Abstract: A switching apparatus allows coupled coils to be dynamically switched in or out of a circuit using small control currents. The apparatus includes at least one latching circuit, one or more control circuits and diodes. The latching circuit may have two bipolar transistors connected in a transistor latch configuration with at least two diodes, such that at least one diode may be connected in series with a base of the each bipolar transistor. The control circuits may be connected to the latch circuit for operating the bipolar transistors. The diodes may be connected in the circuit for protecting the latching and control circuits from being exposed to high voltages and currents during the turn-off or turn-on of the inductor coils. This allows overall efficiency levels to be maintained while changing the inductance of the circuit as per requirements. The circuits may be used in switch mode power supplies (SMPS).

  • Patent number: 8610410
    Abstract: The present invention relates to a power converter circuit for operating on a DC input voltage comprising a forward ferrite-core transformer having at least two primary windings and at least one secondary winding, at least one automatic switching device provided between the primary windings, a current sense circuit provided between the first primary winding and the automatic switching device, and a control unit having a voltage sense circuit, the control unit being connected to the automatic switching device and the current sense circuit and being configured to operate the automatic switch on the basis of an input parameter, thereby controlling the out put voltage.
