Fault Detection Method Using a Convolution Neural Network for Hybrid Active Neutral-Point Clamped Inverters

Abstract: This article presents an open-switch fault detection method for a hybrid active neutral-point clamped (HANPC) inverter based on deep learning technology. The HANPC inverter generates a three-level output voltage with four silicon switches and two silicon carbide switches per phase. The probability of open fault in switching devices increases because of the large number of switches of the entire power converter. The open-switch fault causes distortion of output currents. A convolution neural network (CNN) compr… Show more

“…Recently, convolutional neural networks (CNNs) have also shown good results in isolating OC faults by using the wavelet transform to extract features from the measured arm and submodule signals [33]. [34] showed how phase-current signals can be used with CNNs for FDI of single OC faults in a three-phase inverter. A very robust classier based on a 1-dimensional CNN is designed in [35], using sub-module output voltages and circulating current as the inputs to the network.…”

“…In another valuable study [69], the CNN method has been selected as a diagnostic tool to detect inverter faults in the PV system and symmetrical/unsymmetrical faults in the distribution line. In [70], the CNN procedure has been represented as a powerful tool to diagnosis OC switch fault in a hybrid active NPC inverter. The ELM and Random Vector Functional Link network techniques, as machine learning applications, identify and classify OC fault in an IGBT utilized in a 3-phase PWM converter [71].…”
