1. A method for operating a regenerative closed loop thermodynamic power generation cycle system, comprising:

  • delivering an exhaust stream from a high-pressure expander;

    splitting the exhaust stream from the high-pressure expander to a first exhaust stream and a second exhaust stream;

    directing the first exhaust stream to a first low-pressure expander, wherein the first low-pressure expander is coupled to a pressurization device through a turbocompressor shaft;

    directing the second exhaust stream to a second low-pressure expander, wherein the second low-pressure expander is coupled to the high-pressure expander and an electrical generator through a turbogenerator shaft; and

    delivering a pressurized fluid stream above a critical point of a working fluid from the pressurization device and providing the pressurized fluid stream to the high-pressure expander.
