An efficient space vector modulation algorithm for AC-AC matrix converters: analysis and implementation

The paper presents a control strategy for matrix converters based on the space vector modulation technique (SVM). A novel and efficient modulation algorithm was developed and implemented using a digital signal processor (TMS320C30). The control scheme calculates the switch on/off intervals in real-time and can generate high switching-frequency control-pulses. A 2 kVA prototype IGBT-based matrix converter was constructed to verify the performance of the modulator. The output voltage and the input current waveforms generated by the converter are shown together with their frequency spectra.
