Abstract
An electronic system can include a charged system and a charging system. The charged system can include a charger and a battery configured to be charged thereby. The charger may be configured to receive power from a charging system that includes a power converter configured to supply power to the charger and a controller configured to control the power converter. The controller may be configured to receive feedback information from the charged system, including one or more voltages. The controller may be further configured to determine an output voltage compensation value for the power converter as a function of the feedback information and to set an output voltage of the power converter as a function of the compensation value. The compensation value and output voltage may be selected to maintain a preselected headroom between a battery charging target voltage of the charger and a voltage supplied to the charger.
