Abstract
- In this paper, three overmodulation techniques for the three-to-five-phase indirect matrix converter (IMC) are proposed. The first technique utilizes only the adjacent large vectors in the sector in which the reference output voltage vector lies. The second technique improves on that by continuously adapting vector elimination in the d_2-q_2 vector space based on the output voltage requirements. The third technique utilizes the ripple in the dc link to further reduce the modulation index of the inverter stage during overmodulation. All three techniques increase the voltage transfer ratio of the three-to-five-phase IMC from 0.788 to 0.923, but with the addition of harmonics generated by a vector in the d_2-q_2 vector space of the inverter stage. Simulation and experimental results from a prototype three-to-five-phase IMC validate the three proposed overmodulation techniques. [ABSTRACT FROM AUTHOR]
