Abstract:

This paper presents an extension theory-based assessment method to perform fault diagnosis for inverters in motor driving systems. First, a three-level neutral-point clamped (NPC) inverter is created using the PSIM software package to simulate faults for any power transistor in the NPC-type inverter. Fast Fourier transformation is used to transform the line current signals in the time domain into a spectrum in the frequency domain for analysis of the corresponding spectrum of features of the inverter for faults with different power transistors. Then, the relationships between fault types and s

Abstract: This paper presents a comparative analysis of fault behaviour in conventional and fault-tolerant five-level NeutralPoint Clamped (NPC) inverters. While conventional multilevel inverter architectures are known for their ability to lower Total Harmonic Distortion (THD) and reduce the need for bulky filters, they often encounter reliability concerns due to a higher component count and challenges in maintaining capacitor voltage balance. In contrast, fault-tolerant inverter designs are developed to improve system dependability by minimizing the impact of faults in power sources or switch

As the electricity conversion switch of electric vehicles, the inverters play an important role in vehicle’s driving and regenerative braking process. Therefore, the research in fault-tolerant control of inverters has important significance. This article applied a 5-phase fault-tolerant inverter into the electric vehicles, and researched its single-phase and double-phase fault-tolerant control.

Multilevel inverters (MLIs) are used on a large scale because they have low total harmonic distortion (THD) and low voltage stress across the switches, making them ideal for medium- and high-power applications. The authenticity of semiconductor devices is one of the main concerns for these MLIs to operate properly. Due to the large number of switches in multilevel inverters, the possibility of a fault also arises. Hence, a reliable five-level inverter topology with fault-tolerant ability has been proposed.

Five-level Neutral Point Clamped (NPC) inverters are widely utilized in high-power and industrial systems due to their ability to generate high-quality output waveforms, minimize Total Harmonic Distortion (THD), and evenly distribute voltage stress across semiconductor switches.

Abstract:

This paper presents a new technique to track the saliency position in a permanent magnet synchronous motor (PMSM) post a single phase open-circuit fault. The PMSM is driven by a fault-tolerant multi-level inverter that is utilized to implement a fault-tolerant control strategy to minimize system performance degradation post the fault.The fault-tolerant multi-level inverter is consisting of a number of insulated-gate bipolar transistors (IGBTs). The dynamic current reponses of the PMSM motor due to the switching actions of these IGBTs are used extract the saliency position. This process is not

Abstract:

A control strategy for a fault-tolerant paralleling active power filter was proposed. The structure and running models of the fault-tolerant paralleling active power filter were given. When the inverter of APF had fault in some phase, the fault structure of the inverter was analyzed. Its fault-tolerant structure was three-phase four-switch. The bridge composed of two capacitors replaced the fault phase for the inverter based on three-phase four-switch. It was important to stay stable for inverter DC-side. The method to stabilize the DC-side voltage was proposed. The controlling strategy for AP

This paper presents an efficient and fast fault-tolerant control scheme for a bidirectional Z-source inverter (BiZSI)-fed induction-motor drive system for vehicular applications. The proposed strategy aims for the fault detection, localization and diagnosis of the proposed system during switch failures in the inverter module. Generally, power–semiconductor switch failures in inverter modules occur due to open- and short-circuit faults. An efficient modulation scheme is proposed and design specifications are thoroughly derived to obtain high voltage gains across the BiZSI network. A suitably fa

Abstract:

Three-level NPC inverters have been widely used in grid-connected systems due to their superior performance compared with two-level inverters, but more switches lead to high fault probability. Meanwhile, the neutral point potential (NPP) fluctuation of the DC link is an inherent problem of three-level NPC inverters. To keep the three-level NPC inverter running stably after single-arm failure, a fault-tolerant control strategy based on an optimised space vector pulse width modulation (SVPWM) is proposed in this paper.

The elevated penetration of renewable energy has seen a significant increase in the integration of inverter-based resources (IBRs) into the electricity network. According to various industrial standards on interconnection and interoperability, IBRs should be able to withstand variability in grid conditions. Positive sequence voltage-oriented control (PSVOC) with a feed-forward decoupling approach is often adopted to ensure closed-loop control of inverters. However, the dynamic response of this control scheme deteriorates during fluctuations in the grid voltage due to the sensitivity of proport

The traction inverter is a crucial power device in the electric vehicle’s powertrain, and its failure is intolerable as it would considerably compromise the system’s safety. For more reliable driving, installing a traction inverter that is sufficiently resistant to electrical failure is inherent. Due to its compact size and the small number of switches incorporated in three-phase four-switch inverter, this modular topology was used to compensate for the open switch’s failure.

Multilevel inverters (MLIs) are used in a variety of industrial applications in high- and medium-voltage systems. The modularity, high-power output from medium voltages, and low harmonic content are some of the advantages of MLIs. The reliability of MLIs is quite important. The reliability is affected by different kinds of faults occurring in the MLIs. In MLI circuits, switching devices are the most vulnerable components and have a major involvement in all types of faults. As an outcome, it is necessary to take proper corrective action in the event of a fault. This work provides a comprehensiv

In this paper, a fault tolerant control method is proposed for a permeant magnet synchronous motor (PMSM) servo drive system with four leg inverters to cope with the open phase fault. As one of common faults in the motor drive system, the open phase fault will degrade the control performance and efficiency. Even serious damage is caused in some extreme cases. Hence, it is meaningful to realize the fault tolerance of the drive system with open phase fault.
