“…In a three-phase DC/AC inverter, a three-phase voltage is usually represented by three scalars. If the three scalars in a three-phase inverter are represented by a composite quantity, the three-phase problem can be reduced to a single-phase problem while reducing the fault signal redundancy and the data-processing capacity [25] . Suppose that the three-phase voltage scalars at the traction inverter output are A U , B U , and C U and satisfy formula (11) 0…”

This study proposes a new method of fault diagnosis based on the least squares support vector machine with gradient information (G-LS-SVM) to solve the insulated-gate bipolar transistor(IGBT) open-circuit failure problem of the traction inverter in a catenary power supply system. First, a simulation model based on traction inverter topology is built, and various voltage fault signal waveforms are simulated based on the IGBT inverter open-circuit fault classification. Second, compressive sensing theory is used to sparsely represent the voltage fault signal and make it a fault signal.The new method has a high degree of sparseness and builds an overcomplete dictionary model containing the feature vectors of voltage fault signals based on a double sparse dictionary model to match the sparse signal characteristics. Finally, the space vector transform is used to represent the three-phase voltage scalar in the traction inverter as a composite quantity to reduce the redundancy of the fault signals and data-processing capabilities. A G-LS-SVM fault diagnosis model is then built to diagnose and identify the voltage fault signal feature vector in an overcomplete dictionary. The simulation results show that the accuracy of this method for various types of IGBT tube fault diagnosis is over 98.92%. Moreover, the G-LS-SVM model is robust and not affected by Gaussian white noise.

“…The synchronous reluctance motors (SynRMs) have recently attracted a lot of attention across a wide range of industrial applications owing to its small size, lower cost, high reliability, high overload ability, high dynamic, great reliability and high power density [1][2][3][4][5][6]. Furthermore, the SynRMs are seen as a better alternative to induction motors and permanent magnet synchronous motors for many applications, such as fans, washing machines and electric vehicles.…”

The capacity to determine how the state variable system would behave during fixed-point and transition operations is a significant enhancement of the model-free control technique. This paper describes a vector control, also called field-oriented control (FOC) based on model-free control approach for a synchronous reluctance motor (SynRM). The high performance of the proposed model-free control (MFC)-based vector control of SynRM drive is evaluated and compared with (FOC) based on classical proportional-integral (PI) controller under diverse conditions. At last, the results reveal the suggested MFC's efficiency and technical advantages, as well as its advantages over the classical PI.

“…Table I shows that to accomplish the same number of voltage levels, inverters need an equal number of main switches and main diodes. As cascaded inverters do not require clamping diodes, they have the smallest component count [1][2][3][4][5][6][7][8][9][10][11][12].…”

Multilevel inverter technology has become the most significant method of energy conversion from DC to AC for uninterrupted power supply. The quality of the power supply depends on the appearance of harmonics, which is considered a problem that needs to be overcome. This paper demonstrates the use of a new modulation technique to reduce the harmonics in both diode-clamped and cascaded multilevel inverters, examining its Total Harmonic Distortion (THD) compared to other PWM methods. Simulations were carried out in MATLAB/Simulink for five-level diode-clamped and cascaded multilevel inverters. The simulation results of both multilevel inverters using the sinusoidal PWM, modified reference PWM, modified carrier PWM, and modified reference and modified carrier PWM methods showed that the latter had the best THD performance for both inverter types, especially for the cascaded multilevel inverter.
