  • 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.
