【 摘 要 】

Matrix converter (MC) is a typical high-power-density converter used in more electric aircraft, in which MC can be used as electric de-icer converter and generation starter converter; this study proposes an analytical spectral calculation method based on three-dimensional (3D) Fourier integral to obtain accurate spectra of both output voltage and input current of a space vector pulse width modulation (SVPWM) MC. The MC is a direct AC–AC power converter without an intermediate DC link; three-phase output is synthesised by three-phase input through nine bidirectional switches. At present, there is no such research on spectral analysis for MC space vector modulation. This study focuses on spectral calculation, by the adoption of 3D Fourier integral, spectral of bidirectional switch duty cycle function, output voltage and input current can be achieved. When analytic spectral solution is obtained, the correspondence between SVPWM and harmonic components is established. Simulation and experimental results are given to demonstrate the theoretical work.
