Power management system for variable load application

TLDR: In this article, a system and method for efficient distribution and conditioning of power to one or more variable loads is described, where a power control module is adapted to monitor the load requirements, both current and future, of variable loads.

Abstract: A system and method for efficient distribution and conditioning of power to one or more variable loads are disclosed herein. Power having a first form is supplied to one or more power conversion units (PCUs) connected to the one or more variable loads. The PCUs are adapted to convert the power from the first form to other forms suitable for use by the components of the destination system. Additionally, a power control module is adapted to monitor the load requirements, both current and future, of the one or more variable loads. Based at least in part on the load requirements, the power control module controls the operation of the one or more PCUs to provide sufficient power to the one or more loads at the appropriate time while minimizing wasted power generation by deactivating any unnecessary PCUs. Additionally, the power control module can, based at least in part on a predicted temporary change in the load requirements, direct one or more of the PCUs to change their output voltages in anticipation of the change in the load requirement, such as by increasing their output voltages to provide additional energy to the one or more variable loads during a temporary increase in power consumption or by decreasing their output voltages during a temporary decrease in power consumption. The present invention proves particularly beneficial when employed to distribute power within a radar system.
