POWER CONVERSION IN VARIABLE LOAD APPLICATIONS

摘要

A power conversion unit and method for efficient conversion of power for 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. Based at least in part on a predicted load requirement of the variable load, the operation of the PCUs can be controlled to provide sufficient power to the one or more loads at the appropriate time while minimizing wasted power generation by deactivating any unnecessary PCUs during a decrease in power consumption or by activating PCUs during an increase in power consumption. Additionally, based at least in part on a predicted temporary change in the load requirements, the PCU can change its output voltage in anticipation of the temporary change in the load requirement, such as by increasing the output voltage to provide additional energy to the one or more variable loads during a temporary increase in power consumption or by decreasing the output voltage during a temporary decrease in power consumption. The present invention proves particularly beneficial when employed to distribute power within a radar system.
