    • Heat engine systems having selectively configurable working fluid circuits are provided. One heat engine system includes a pump that circulates a working fluid through a working fluid circuit and an expander that receives the working fluid from a high pressure side of the working fluid circuit and converts a pressure drop in the working fluid to mechanical energy. A plurality of waste heat exchangers are each selectively positioned in or isolated from the high pressure side. A plurality of recuperators are each selectively positioned in or isolated from the high pressure side and the low pressure side. A plurality of valves are actuated to enable selective control over which of the plurality of waste heat exchangers is positioned in the high pressure side, which of the plurality of recuperators is positioned in the high pressure side, and which of the plurality of recuperators is positioned in the low pressure side.

    • Aspects of the invention provided herein include heat engine systems, methods for generating electricity, and methods for starting a turbo pump. In some configurations, the heat engine system contains a start pump and a turbo pump disposed in series along a working fluid circuit and configured to circulate a working fluid within the working fluid circuit. The start pump may have a pump portion coupled to a motor-driven portion and the turbo pump may have a pump portion coupled to a drive turbine. In one configuration, the pump portion of the start pump is fluidly coupled to the working fluid circuit downstream of and in series with the pump portion of the turbo pump. In another configuration, the pump portion of the start pump is fluidly coupled to the working fluid circuit upstream of and in series with the pump portion of the turbo pump.

    • Provided herein is a heat engine system and a method for generating electricity. The heat engine system contains a turbo pump throttle valve fluidly coupled to a working fluid circuit and disposed upstream of a turbine inlet on a drive turbine of a turbo pump, a primary governing loop controller configured to maintain a desirable value of the inlet pressure by modulating the turbo pump throttle valve, and a secondary governing loop controller configured to detect an undesirable value of the inlet pressure and to increase the inlet pressure by modulating the turbo pump throttle valve. A start pump bypass valve may be fluidly coupled to a bypass line and disposed downstream of a pump outlet on a start pump and/or a turbo pump bypass valve may be fluidly coupled to the bypass line and disposed downstream of the turbo pump.
