The produced voltage of photovoltaic (PV) system is largely affected by environmental variables, such as light intensity and temperature. The PV power conditioning system is required to regulate output ac voltage for broad input voltage variations. This article proposes a new single-phase nonisolated PV inverter with wide input voltage range, due to its buck-boost voltage inversion in a single-stage. The most standout feature of the proposed inverter is its simple and compact construction, as it can be fabricated by adding second-order input and output LCfilters to an integrated three-leg inverter module. A small value film capacitor is added across inverter module, providing energy storage and also acting as natural lossless snubber for switching devices. It contributes a shared-ground point between PV panel and grid-neutral, eliminating the common-mode voltage variations (at high-frequency) by clamping the voltage between grid and PV panel. Therefore, it can successfully eliminate the flow of leakage current by parasitic capacitors of transformerless PV inverter systems. The proposed inverter can provide reactive power support. Extensive experimental results are performed on a laboratory-built hardware prototype to confirm the practicality of the proposed PV inverter.

This article proposes a seven-level common-ground-type (CGT) transformerless inverter with a boosting feature for solar photovoltaic (PV) applications. The proposed topology's common ground feature eliminates the crucial ground leakage current caused by the varying common mode voltage in grid-connected PV inverters. Unlike the conventional and recent CGT inverters, the proposed inverter requires only two capacitors of voltage rating lower than the inverter's peak output voltage. Thereby, the semiconductor devices experience reduced voltage stress resulting in lower power losses. Further, the circuit description and operating principle are presented in detail. The detailed comparative assessment of the proposed and its counterpart topologies is carried out to highlight the superior features of the former such as lower component count, least average number of conducting devices, fewest number of devices in the charging path, self-voltage balancing of the capacitors and reduced capacitor voltage diversity factor. In addition, it will be shown that the proposed inverter cost and footprint requirements are lesser than the available competent solutions. Furthermore, a detailed reliability assessment with fault tolerant operation is presented. Finally, the experimental results of the proposed inverter's grid-connected and stand-alone operations are elucidated to validate its feasibility.

In this article, two open problems of the existing bounded uncertainty and disturbance estimator (UDE)-based robust control method are investigated: the input constraint with multiple control inputs, and the performance degradation caused by the introduced additional time-varying control variable. A modified bounded UDE-based robust control method is developed for the multiple-input–multiple-output (MIMO) system with the inputs constrained by a general positive defined matrix, which is a more general condition of the norm constraint for control inputs. A nonlinear design is further proposed to modify the direct multiplication of the additional time-varying variable to mitigate the performance degradation of the existing bounded UDE-based robust control, and the guidance of the nonlinear design procedures is provided. Inputs constraint, uncertainties, and disturbances are handled simultaneously for MIMO systems with the mitigation of the integral windup issue. The proposed control design is applied to the vector control of a permanent magnet synchronous motor drive system, and the experimental studies are provided to validate the proposed design under voltage constraint with both normal operation and voltage constraint triggered.

This article presents a high-frequency model to analyze leakage current (LC) in electronic-pole-changing (EP-C) induction motor drives (IMDs). LC flows through parasitic capacitances in inverter-fed drive systems, resulting from the equivalent common-mode voltage (E-CMV) generated by the inverter's high-frequency pulsewidth modulation (PWM) strategy. Furthermore, for EP-C operation, different PWM strategies are required to operate IMD in different pole-phase combinations. Additionally, high-frequency LCs contribute to electromagnetic interference in the system. Thus, it becomes essential to analyze in all different IMD's pole-phase combinations. This is because nature of these patterns is critical for both steady-state and pole transition operations in EP-C IMD, as they may lead to drive failure due to the breakdown of parasitic capacitances. Consequently, this article proposes an analysis to examine E-CMV and LC patterns using the switching function concept and a high-frequency IMD model for EP-C IMD operation. Furthermore, this analysis assists in deducing PWM strategies with optimal switching frequency ranges for smoother EP-C operation. To demonstrate the proposed analysis, two pole-phase combinations (3-ϕ, 12-pole, 9-ϕ, 4-pole) in EP-C IMD are considered with different PWM techniques. The analysis is conducted in the ANSYS simulation environment and verified experimentally.

This article develops a universal, accurate steady-state model suitable for the current-fed dual active bridge (CFDAB). Unlike a voltage-fed dual-active-bridge converter, modeling of the CFDAB converter is not straightforward due to the presence of additional buck/boost stage on the low-voltage side. This article presents for the first time exhaustive information on steady-state characteristics of the CFDAB for the entire operating region under pulsewidth plus phase shift (PPS) modulation. The steady-state behavior is obtained analytically using the harmonic state-space (HSS) model. The developed HSS model is advantageous over the popular generalized averaging method since it is easier to extend the former model to numerous high-order harmonics than the latter. The presented model outputs accurate steady-state waveforms. The model is used to study the characteristics of some important electrical quantities, such as peak current, rms current of the high frequency link, output current ripple, for the entire range of all degrees of freedom at one go. The exhaustive experimental results confirm the analytical model.

The electrification of transportation is a pivotal step toward sustainable and environmentally conscious mobility. However, as the adoption of electric vehicles (EVs) and associated technologies continues to grow, the need for effective strategies to manage end-of-life components becomes increasingly crucial from both sustainability and economic standpoints. Obtaining essential rare-Earth (RE) materials such as cobalt, lithium, neodymium, and terbium has become progressively more difficult and costlier. Furthermore, the extraction and processing of these materials produce significant carbon emissions and release harmful toxins. The economic value of the materials and components in EVs is generally 20%–30% higher than that of conventional internal combustion engine based vehicles due to the increased use of lightweight and RE materials in batteries and electric motors. This article aims to address the imperative of closing the loop on the circular economy within the realm of transportation electrification, with a specific focus on electric drives (i.e., power electronics and electric machines) as well as batteries with reuse, repurposing, and recycling technologies.

In this article, a novel single-phase integrated bidirectional onboard charger based on a symmetrical six-phase induction motor is proposed. The charger has grid-to-vehicle, vehicle-to-grid, and vehicle-to-vehicle charging capabilities. In the proposed charger, the machine windings are employed as inductors, and the six-leg converter accomplishes ac–dc and dc–dc conversions. The windings of a six-phase machine form two sets of three-phase windings. One set of three-phase windings is used as grid filter inductance in single-phase ac–dc conversion. The remaining set serves as filter inductances for the dc–dc converter, which is a bidirectional, noninverting buck-boost converter. Compared to existing single-phase ac chargers, the proposed charger circuit can be easily reconfigured to accept both ac and dc sources. Reconfiguration from vehicle driving to battery charging mode does not require any extra fast switching elements or passive components. An efficient control technique is used to avoid redundant switching losses in a dc–dc converter. A scaled-down laboratory prototype is built and tested to verify the proposed hypothesis.

Resilience is an essential property for resisting cyber-attacks and ensuring the stability of industrial cyber-physical systems (ICPSs). This article proposes a novel digital twin-based resilient model predictive control (MPC) method for ICPSs with intelligent false data injection (FDI) attacks. First, a general digital twin is developed based on the long short-term memory model to predict the next system state. Specifically, the sensor measurements are utilized to predict the actual system state when the system is running normally; when the system is under attacks, the digital twin turns to a self-iteration mode and starts a roll-back mechanism to predict the system state by using the historical datasets. Then, a resilient Lyapunov-based MPC method with the predictive model established by the digital twin is designed to resist intelligent FDI attacks and the stability of the closed-loop system is ensured. Finally, the experiments with three types of intelligent FDI attacks are conducted on a self-build hardware-in-the-loop platform to test the performance of the proposed control framework for the industrial two-continuous stirred tank reactor-in-series process. The results show that the digital twin can accurately replicate the system behaviors and the proposed control scheme is efficient to resist cyber-attacks and guarantee the system stability.

Constant power (CP) charging profile in inductive power transfer (IPT) systems offer significant advantages, such as reduced charging time and lower thermal requirements, compared to constant current charging. In addition, achieving a high voltage gain from a CP-IPT charger is essential for high voltage battery charging applications. However, improving efficiency in CP-IPT chargers operating at high voltage gain remains unexplored. In this article, we propose a novel load matching scheme for CP charging, which utilizes active shunt compensation on the secondary side to enhance efficiency at higher voltage gains. Furthermore, we analyze design considerations to ensure soft-switching operation. The steady-state characteristics of the proposed wireless charger topology are derived analytically, and the scheme is validated on a 150 W experimental setup. We also demonstrate the converter's protection during an open circuit fault on the load through experimental study. The proposed topology enables high-efficiency power transfer throughout the CP charging mode, making it particularly suitable for stationary charging applications of high voltage batteries.
