Abstract
According to an aspect, an adaptor may include a converting unit configured to convert a source voltage to an output voltage to be provided to a computing device via a cable. The converting unit includes a transformer having primary windings and secondary windings. The adaptor includes a current sense unit configured to obtain a current sense signal, where the current sense signal indicates an output current produced by the secondary windings of the transformer. The adaptor includes an IR drop detection unit configured to determine a feedback signal representing a voltage drop caused by the cable based on the current sense signal and the output voltage of the converting unit, and a control unit configured to adjust the output voltage of the converting unit to account for the voltage drop represented by the feedback signal.
