A novel fault‐detection methodology of proposed reduced switch MLI fed induction motor drive using discrete wavelet transforms

Abstract: Summary Induction motors are typically promoted in industrial applications by adopting energy‐efficient power‐electronic drive technology. Multilevel inverters (MLI) have been widely recognized in recent days for high‐power, medium‐voltage‐efficient drives. There has been vital interest in forming novel multilevel inverters with reduced switching elements. The newly proposed reduced‐switch five‐level inverter topology extends with fewer switches, low dv/dt stress, high efficiency, and so on, over the formal mu… Show more

“…CM of brushless DC motors is investigated based on energies for characteristic frequencies based on both STFT and WT in [17]. A decomposition rate is used in [18] for CM of electric drives based on WT. RMS and Kurtosis are calculated for the WT coefficients for broken bar fault detection in electric drives and combined with a neural network for fault classification in [19].…”

“…The signal-based fault diagnosis method depends on the signal distortion caused by the fault [14]. The distinguishing fault features are extracted by signal processing methods such as Fourier transform [15][16][17], wavelet decomposition [18,19], and variational modal decomposition [20,21]. The extracted features are often used as input for an intelligent algorithm, and the intelligent algorithm finally identifies the fault types.…”
