Abstract
An electrical power supply includes a power circuit for providing power to a load via a conductor, and a control circuit. The control circuit is configured to set an output voltage of the power circuit at different values to cause the load voltage at the load to change, sense an output current of the power circuit corresponding to each different value of the output voltage, determine an electrical resistance of the conductor based on the different output voltage values and their corresponding output current values, and set the output voltage of the power circuit at a defined value based on the determined resistance to compensate for a voltage drop of the conductor when the power circuit provides power to the load and to regulate the load voltage at the load at a desired value. Other example power supplies, control circuits and/or methods of regulating load voltages are also disclosed.
