Abstract

Systems and methods for efficient power regulation of a power transmission element having a power input and a power output. An output monitor is configured to monitor at least one system parameter and an input controller is configured to control the power input. A feedback mechanism may be provided to send feedback signals relating to the at least one system parameter to the input controller. The input controller may adjust the power input of the power transmission element to control voltage drop across the power transmission element and control temperature and heat loss from the system.
