Performance of SVM algorithm implemented on fixed point ADSP-BF527

With the availability of low cost high performance DSP chips characterized by the execution of most instructions in one instruction cycle, complicated control algorithms can be executed with fast speed, making very high sampling rate possible for digitally-controlled inverters. Control methods, which generate the necessary pulse space vector modulation (SVM) have been discussed extensively in literature. These could be classified as voltage controlled and current controlled SVM. All these methods aim at generating inverter output voltage without low-order harmonics. This paper presents theoretical and experimental aspects for DSP-based algorithm to generate space vector modulation (SVM) signals.
