Abstract
A power adapter includes a primary side and a secondary side. The primary side rectifies an alternating current voltage. The secondary side is coupled to the primary side, provides a direct current voltage of a specific voltage level to a cable. The second side includes a sensing resistor, and a compensation circuit. The compensation circuit monitors a voltage level across the sensing resistor, and injects a current into the cable based on the voltage level across the sensing resistor.
