Abstract:
1. An automotive electrical system comprising: a smart junction box connected to a non-critical load; a boost converter connected to the smart junction box, the boost converter being directly connected to a critical load and not to the non-critical load; such that the critical load is electrically isolated from the non-critical load at least in part by the smart junction box and such that the boost converter adjusts the voltage being supplied to the critical load and not to the non-critical load to provide separate control of the critical load and the non-critical load; wherein the smart junction box is configured to selectively control the operation of the non-critical load and wherein the smart junction box is further configured to selectively activate and deactivate the boost converter; wherein the boost converter is configured to determine an occurrence of a voltage transient caused by an event associated with the non-critical load, and to responsively and when enabled by the smart junction box, boost a voltage supplied to the critical load.
