摘要: Operation of multipulse converters can be conveniently described in the frequency domain by using their voltage and current mapping functions. Applications such functions include input impedance modeling rectifiers, analysis harmonic transfer coupling through high-voltage dc transmission lines, distortion rectifiers under unbalanced and/or distorted source conditions. The existing approach to spectral requires small-signal assumption commensurability between ac fundamental frequency. A new method based on double-Fourier series is presented. proposed overcomes limitations conventional Fourier provides a more rigorous basis for frequency-domain converters.
