  • Single solid state power supply for multiple engine systems
    Patent number: 11008993
    Abstract: A power generation system is disclosed. The power generation system may include a first engine and a second engine. The power generation system may include an alternating current (AC) generator coupled to the first engine and a solid state power supply connected to the AC generator via a first circuit. The power generation system may include a first energy storage device associated with the first engine, connected to the solid state power supply via a second circuit, and a first engine control module (ECM) associated with the first engine, connected to the solid state power supply via the second circuit. The power generation system may include a second energy storage device associated with the second engine, connected to the solid state power supply via the second circuit, and a second ECM associated with the second engine, connected to the solid state power supply via the second circuit.

  • Fan powered by an alternating current generator associated with a liquid-cooled engine of an engine system
    Patent number: 10995653
    Abstract: A generator set is disclosed. The generator set may include a liquid-cooled engine and an alternating current (AC) generator coupled to the liquid-cooled engine. The generator set may include an AC fan associated with the liquid-cooled engine and connected to the AC generator via a relay and an engine control module (ECM) associated with the liquid-cooled engine and connected to the AC fan via the relay. The generator set may include an engine temperature sensor associated with the liquid-cooled engine and connected to the ECM via a first circuit and an engine air temperature sensor associated with the liquid-cooled engine and connected to the ECM via a second circuit.
