摘要：

Various methods for sampling of voltage and current signals in electrical drives are analyzed and compared. Two new methods for sampling the discontinuous voltage and current signals in a pulsewidth modulation drive are proposed. The methods are based on sampling the instantaneous values and locally averaged values (over one carrier period) of signals. Analytical expressions for adjustment of digital current regulators and achievable bandwidths with the various sampling methods are derived, The results are experimentally verified.
