Patents by Inventor Robert Porter Edwards

Robert Porter Edwards 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: 10018126
    Abstract: A power generating set includes an engine operable in response to a flow of fuel to produce a flow of exhaust gas, a generator coupled to the engine and operable in response to operation of the engine to produce a total electrical power, and a primary load electrically connected to the generator to receive a portion of the total electrical power, the primary load having a cyclical pattern. A battery bank is selectively connected to the generator to receive a portion of the total electrical power and an insulated-gate bipolar transistor (IGBT) is positioned to selectively transition between a connected state and a disconnected state. The battery bank is connected to the generator to charge the battery bank when the IGBT is in the connected state and is disconnected from the generator when the IGBT is in the disconnected state.
    Type: Grant

  • Patent number: 9308910
    Abstract: A power generating set includes an engine operable in response to a flow of fuel to produce a flow of exhaust gas. A generator is coupled to the engine and is operable in response to operation of the engine to produce a total electrical power, a primary load is electrically connected to the generator to receive a portion of the total electrical power, and a secondary load is selectively connected to the generator to receive a portion of the total electrical power. An insulated-gate bipolar transistor (IGBT) is positioned to selectively transition between a connected state and a disconnected state. The secondary load is connected to the generator when the IGBT is in the connected state and is disconnected from the generator when the IGBT is in the disconnected state.
