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) incorporated with interface facilities. The control scheme is characterised by a real-time calculation of switchg on/off intervals and a capability to operate at high switching frequency. To verify the validity of the real-time modulator, an analogue simulation of a matrix converter was built. The output voltage waveforms generated by this converter are shown in association with their frequency spectra. The results agree well with the traget specification.
