Abstract:
A system and method for estimating current in a DC-DC converter are provided that estimate an output current of the DC-DC converter more accurately by correcting an output voltage of a CT sensor at an input terminal as a part of a current map and an efficiency map. The current map and the efficiency map are configured in a 2D form, since the output voltage of the CT sensor varies depending on the PWM duty.
