System level current limiting

摘要

A power distribution system, having distributed intelligence, includes a controller in communication with a plurality of rectifiers/power conversion units (PCUs). The controller and rectifiers/PCUs communicate with each other to generate system level current limit via a single control point, where system level current limit is accomplished by controlling the individual current limits of the rectifiers/PCUs. The system level current limit operating in combination with ambient temperature sensors, battery temperature sensors, load current sensors, and battery re-charge current sensors to control the operation of the system. The above sensors are also used in combination with a system level voltage control.
