Abstract
Two new methods for sampling the discontinuous voltage and current signals in a PWM invertor-fed AC motor drive are proposed. The methods are based on sampling the instantaneous values and locally averaged values (over one carrier period) of signals. The analytical expressions for adjustment of digital current regulators and achievable bandwidths with the different sampling methods are derived. The results are experimentally verified.
