Abstract
Examples of the disclosure include a power system comprising an input to receive input power, an output to provide power to a load, a sensor configured to provide load information indicative of power drawn by the load, a plurality of power modules, each having a power module input configured to be coupled to the input, and a power module output configured to be coupled to the output, and a controller coupled to the power modules and the sensor, and being configured to control the power modules to provide power to the output, receive the load information from the sensor, select, based on the load information, at least one power module to maintain in an active state to provide power to the output, and deactivate each power module other than the at least one power module based on selecting the at least one power module to maintain in the active state.
