摘要：The need for control algorithm of low switching losses and harmonic distortion is becoming more
and more urgent, especially when the high frequency devices are used in the power electronic
systems . So a new space vector modulation (SVM) was introduced, which has the virtue of low
switching losses and harmonic distortion. And the algorithm model was built to study its operation
in Simulink. Simulation results, including the output voltage waveforms and the spectrum of the
output line-to-line voltage, were given under various modulation indices and N (the ratio of carrier
frequency to modulation wave frequency). The experiments of the algorithm had been carried out
based on TMS320F2812 DSP. It is shown that the proposed SVM makes doubled calculations at
specified switching frequency. And the output THD of it is better than that of 7-segment SVM.
