1. A thermal management system configured to manage temperature in a temperature-sensitive region of an electrical device, the system comprising:

  • a thermoelectric device configured to transfer thermal energy between a main surface and a waste surface upon application of electric power to the thermoelectric device, wherein the main surface of the thermoelectric device is in substantial thermal communication with an electrical conductor, wherein the electrical conductor is configured to deliver electric power to or from an electrical device, and wherein the electrical conductor is capable of serving as a conduit for conducting thermal energy between a temperature-sensitive region of the electrical device and the thermoelectric device;

    a controller comprising a control algorithm configured to monitor a thermal gradient created during operation of the electrical device across the temperature sensitive region and to adjust electric power delivered to the thermoelectric device such that the thermal energy transferred to or away from the temperature-sensitive region of the electrical device reduces or eliminates the thermal gradient created during operation of the electrical device across the temperature sensitive region.
