Abstract
Various methods for sampling of voltage and current signals in electri cal 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 instantaneou s values and locally averaged values (over one carrier period) of sign als. Analytical expressions for adjustment of digital current regulato rs and achievable bandwidths with the various sampling methods are der ived, The results are experimentally verified.
