Abstract
An electrical power and thermal management system may include a power plant operable to provide power to an electrical generation device. The system may include at least one conversion/distribution assembly configured to provide electrical power to a first electrical bus. The system may also include a thermal management system configured to circulate coolant to at least one heat source. A controller may be in communication with the power plant, the electrical generation device, the conversion/distribution assembly, the electrical power bus, and the thermal management system. The controller may be configured to integrally manage electrical and thermal steady and transient demands, wherein the controller is operable to selectively distribute power to the electrical power bus and regulate produced thermal energy in response to electrical and thermal demands, respectively.
