Ezekiel Poulose Aikkaravelil 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 power DC SSPC with capability of soft turn-on large capacitive loads
    Patent number: 8716997
    Abstract: Pre-charge circuitry allows capacitive loads connected to a solid state power controller to be gradually charged up by a PWM, generated with a cycle by cycle current limit, switching a single MOSFET in series with an inductor, before the SSPC is turned on. The pre-charge circuitry may require only three additional components, e.g., a MOSFET, an inductor and a diode, along with a designated MOSFET gate driver.
    Type: Grant

  • SSPC distribution system and control strategy
    Patent number: 8704574
    Abstract: A power distribution system includes the use of a master digital signal processor (DSP) and two slave DSPs connected to the master DSP. The slaves DSPs may be connected to each of a plurality of solid state power channels (SSPC) controlling power distribution functions to each of the channels. A power control strategy may use one power supply for the master DSP, a second power supply shared between the slave DSPs, and a third power supply shared between each of the SSPC channels.
