Abstract :
In this paper, low-frequency control technology of SPWM inverter was studied theoretically, and the new rule of chosen carrier ratio and relevant equation were produced seriously for optimization of multi-mode modulation technology. On this basis, experimental system of the low-frequency of inverter was built with TI TMS320LF2407A DSP as control core. Finally, relevant experimental research was implemented. The results show that the new modulation can effectively cope with the harmonic, the output waveform instability problem and so on in low frequency.
