Compared with active control, the passive method is more rugged and reliable in driving multistring LEDs with current balance. This paper figures out that it takes a large number of compensation components for the reported inductivepower-transfer (IPT) converter with LCC-CLCL compensation to drive multistring LEDs with current balance. To address this issue, a much simpler IPT converter with S-S compensation is proposed to drive multistring LEDs with current balance. A comparative study on these two IPT converters is performed to verify that the proposed S-S IPT converter shows an advantage in component count while maintaining the current balance capacity.

A novel control strategy of direct current control is proposed to improve the performances of electric springs (ESs) based on current-source inverters (CSIs). The proposed control can realize the functions of voltage regulation, harmonic suppression, and power factor correction (PFC) at the same time. The topology of the ES with CSI is described firstly, then its operating principles are analyzed in detail. A cascade generalized integrator (CGI) is used to construct the quadrature signal generator (QSG). Compared with the QSG based on second-order generalized integrator (SOGI), the proposed CGI-QSG can construct quadrature signals with completely consistent waveforms, and can extract the fundamental component of critical load (CL) current more quickly and effectively. The active and reactive power of ES are decoupled by dq0 transformation to realize multiple functions simultaneously. Finally, the effectiveness of the proposed control is verified by simulation and experimental results in the case of over-voltage and under-voltage respectively.

When optimal switching vector (OSV) model predictive control (MPC) is implemented to a three-phase inverter, the control input is selected from eight switching vectors (vi). This set of vi has merely two-level amplitude with a 2π/6 phase difference. Higher phase or amplitude resolution of vi anticipates better power quality. This paper presents a bisection algorithm to tune the resolution of OSV for power quality improvement. Three user-defined gains (x, y, n) are provided to quantitatively set the phase/amplitude resolution of the OSV using derived explicit formulas. Experiments validate the effectiveness of this algorithm.

In the neutral-point ungrounded distribution network, the non-linear characteristics of the magnetizing inductance of the electromagnetic voltage transformer (PT) are easy to saturate under certain conditions, resulting in ferromagnetic resonance overvoltage, which seriously affects the safe operation of the system. Aiming at the 10 kV neutral point ungrounded system, this paper proposes a method for the neutral point of the distribution network to inject the harmonic elimination resistive current to suppress the ferromagnetic resonance, and the selection of the optimal value of the resonance elimination injection current is explained. Inject a harmonic elimination current into the neutral point of the system to quickly consume grid resonance energy and eliminate ferromagnetic resonance. Through simulation verification, it is found that the proposed method only needs to inject the harmonic elimination current into the neutral point of the system for a short time to make the distribution network out of resonance, and the zero-sequence voltage returns to zero. The time required for the grid to resume normal operation is the shortest.

Synchronous condensers are commonly-used source devices for the purpose of providing voltage support in the renewable energy generation system, using power electronic devices (PEDs) as the interface connected to the grid. It has been pointed out that the grid-connected PEDs may result in small signal instability issues, especially in weak grids. However, how the synchronous condensers influence the small signal stability of the multi-infeed power electronic system (MIPES) has not been theoretically revealed. This paper aims at filling this gap. We demonstrate that the synchronous condensers can be simplified as an equivalent inductance connected to an ideal voltage source in the concerned sub/super synchronous issues caused by PEDs. On this basis, the interconnection of synchronous condensers is equivalent to increase the grid strength and thus improving the system small signal stability, wherein the power grid strength (or small signal stability margin) is our previous work, quantified by the generalized short-circuit ratio (gSCR). The validity of the theoretical analysis proposed in this paper is verified by a two- area four-machine system.

Si/SiC hybrid switch offers an effective tradeoff between cost and performance, but suffers from complex switching processes and limited analytical theory. It is highly desirable to build a complete behavior model to investigate and characterize switching behavior for Si/SiC hybrid switch. In this paper, a Finite State Machine (FSM) based modeling method is proposed to analyze the switching behavior of Si/SiC hybrid switch. Based on the principle of circuit equivalence, the switching transient of the gate-controlled power device is innovatively divided into Voltage Source Mode (VSM) and Current Source Mode (CSM). The behavior model is developed with full consideration circuit stray parameters and is verified by a double-pulse test, which exhibits excellent validity. Furthermore, the proposed method not only provides a reference for switching behavior analysis and loss prediction of Si/SiC hybrid switches, but also can be applied to multiple devices in parallel which means it has excellent extensibility performance.

This paper proposes a model predictive control method based on Kalman filter (MPC-KF) for solving the challenges in simultaneous control of output current tracking, capacitor voltages balance, and harmonic circulating currents suppression, and the operation reliability affected by the damaged sensors regulated modular multilevel converter (MMC), which aims to realize the multi-objective control, enhancing the operation reliability of MMC system. Firstly, the MPC principle of MMC is described. Then, the capacitor voltage prediction-correction strategy based on Kalman filter with only arm current sensor is proposed to obtain the capacitor voltage correction value, instead of using lots of submodule(SM) voltage sensors. In this sense, the reliability under sensor failures of system can be improved. Finally, compared with the SM voltage estimation strategy with single voltage sensor and the conventional SM capacitor voltage measurement strategy, simulation studies are illustrated to demonstrate the feasibility and effectiveness of the proposed MPC-KF method for MMC.

This paper presents a study on the influence of gate parasitic inductance on the SiC MOSFET switching performance. A switching transient equivalent circuit model that takes gate parasitic inductance into consideration is given to assess the SiC MOSFET switching characteristics. Then, the relationship between the voltage overshoot and the gate parasitic inductance is discussed, which can offer better insight into the switching performance when the gate parasitic inductance is varied. It is concluded that the local minimum of the voltage overshoot exists at a relatively large gate parasitic inductance. Furthermore, the analysis is substantiated by experimental results of the double pulse dynamic test platform. Based on this, the method for the gate drive to improve the switching performance of the SiC MOSFET is recommended.

The energy management strategy of fuel cell electric vehicle can greatly influence the performance of vehicle, so a lot of research in this field were done by researchers. In order to improve the adaptability to complex work conditions of traditional strategies, the work condition recognition methods based on intelligence algorithms were introduced to energy management strategies. However, there are a lot of disadvantages of present recognition methods, such as low recognition accuracy and low generality. Aiming at solving these problems, an optimized fuzzy energy management strategy based on micro-trip recognition is proposed in this paper. In this strategy, firstly the work conditions prepared for recognition are divided into several micro-trips to improve the accuracy of recognition. Then, the strategy is simulated on the simplified power system built in this paper and compared with the simulation result of a general rule-based strategy. The better performance of the strategy proposed proves the effectiveness and optimality of this method.
