Abstract :
A dual sample-rate method based on d-q transformation is presented. The controversy of limited DSP (digital signal processor) performance and accurate harmonic acquisition has been solved perfectly. A 16 bits fixed-point conventional DSP can meet the requirement of active power filter application. The theoretic analysis and design are confirmed by simulation and experiment.
