1. A downhole power generation system comprising:

  • an energy source that provides input energy;

    a hydraulic circuit communicably coupled to the energy source to receive the input energy at a hydraulic pump arranged within the hydraulic circuit, wherein the hydraulic pump circulates hydraulic fluid throughout the hydraulic circuit;

    a hydraulic motor arranged in the hydraulic circuit;

    a flow regulation device interposing the hydraulic pump and the hydraulic motor within the hydraulic circuit, wherein the flow regulating device receives hydraulic fluid flow from the hydraulic pump and provides a regulated hydraulic fluid flow directly to an inlet of the hydraulic motor which converts the regulated hydraulic fluid flow into a power input;

    andan electrical generator communicably coupled to the hydraulic motor, wherein the electrical generator receives the power input and generates electrical power.
