Line current harmonics of three‐level neutral‐point‐clamped electric multiple unit rectifiers: analysis, simulation and testing

IET Power Electronics, 2014
The harmonic spectra of the AC supply currents of electric multiple units (EMUs) employing three‐level neutral‐point‐clamped converters are discussed in this study. The analytical expressions of high‐order harmonics because of high‐frequency three‐level phase‐opposition disposition pulse‐width modulation are derived by using double Fourier series and a
