摘要：
An apparatus and method corrects for zero ampere level current fluctuations in a current signal. First and second acquisition circuitry generate respective current and voltage data samples of the current signal. Current fluctuation data samples representative of zero ampere level deviations of the current signal are extracted corresponding to Off-periods of the current signal. The current fluctuation data samples of the Off-periods are interpolated to generate current fluctuation data samples representative of zero ampere level deviations of the On-periods of the current signal. The Off-period and On-period current fluctuation data samples are subtracted from the current data samples of the current signal to generate corrected zero ampere level current data samples.
