Abstract
The present invention relates to a method for compensating a current of a DC/DC converter that detects an average value of a pulsatory current that is output as a chopping wave form from an inductor that is used in a DC/DC converter to compensate an offset value in real time. A method for compensating a current of a DC/DC converter can include analyzing a PWM signal for a switching DC-DC converter, if the PWM signal is on, comparing a delay time with a rise half cycle size between a detected current and a real current that is output by an inductor, calculating a current variation amount and determining an offset compensation value for compensating a current variation amount according to the comparison result of the rise half cycle size and the delay time, and applying the offset compensation value to compensate the detected current of the inductor.
