With the trend toward more electrical aircraft, Silicon Carbide power switches could be heavily used for high temperatures applications within the aircraft. The assessment of the reliability of such power electronic components is a key element for the qualification process. In this study we focused on the reliability of the MOSFET gate oxide which is known to be the more fragile part of these components.

The modern large wind turbines (WTs) are subject to large asymmetric loads, as a result of rotational wind field sampling, wind shear, tower shadow and yaw misalignment. Such asymmetric loads will produce large fatigue damage to blades, hub, shaft and yaw bearing. To mitigate such problem, sliding mode control (SMC) is applied to design individual pitch control (IPC) strategy of WTs in this paper. First, an extended linear model of WT accounting for dynamics of actuators and integral of output errors is derived for control design. Afterwards, a SMC-based IPC strategy is proposed for asymmetric load reduction. Poles assignment method is used to design the SMC switching function, and terminal sliding mode method is utilized to obtain the control law. Finally, the control performance of proposed method is compared to traditional collective pitch control (CPC) and proportional-integral (PI)-based IPC through simulations using FAST software. The simulation results show that the proposed SMC-based IPC can further reduce asymmetric loads compared to CPC and PI-based IPC in both steady and turbulent wind conditions.

A bidirectional cell-to-cell balancing structure using two switches per each cell shows good balancing ability, but many switches lead to increase of the cost and size. To reduce the number of switches, this paper proposes a new cell-to-cell balancing circuit with a center-cell concentration structure. The proposed circuit collects the charges of the overcharged cell into the center-cell, and then the collected charges are redistributed to the other cells. The proposed circuit has unidirectional balancing structure with single switch per each cell, but it can achieve competitive balancing ability compared to bidirectional structure. In this paper, the operational principles of the proposed circuit are analyzed, and the comparison between the proposed and conventional circuits is shown. To verify the validity of the proposed circuit, experiment with 8 batteries is carried out, and the experimental results show the improved cell balancing ability although one switch is used per each cell.

This paper presents a division-summation (D-Σ) digital control for a three-phase transformerless bi-directional photovoltaic inverter with wide inductance variation, which can eliminate the leakage ground currents due to panel parasitic capacitance. The bi-directional inverter fulfilling grid connection and rectification with power factor correction has been implemented in the laboratory. The proposed D-Σ approach summarizes the inductor-current variations over one switching cycle to derive control laws directly, which can overcome limitations of d-q transformation. With the digital control, the inverter can deal with wide inductance variation, reducing core size significantly. In the design and implementation, the inductances corresponding to various inductor currents are measured and tabulated into a single-chip microcontroller for tuning loop gain cycle by cycle, ensuring stable operation. Simulated and Measured results from a 10 kVA 3φ bi-directional inverter are presented to confirm the feasibility of the discussed control approaches.

Two basic structures are generally employed in magnetically-coupled resonant wireless power transfer (MCR-WPT), i.e. the two-coil structure and the four-coil structure. The equivalent circuits of these two structures are demonstrated and the expressions of the transfer efficiency, ignoring the source internal resistance loss, are obtained. Two important factors are introduced to facilitate analysis, namely the transfer quality factor and the load matching factor. The larger the transfer quality factor is, the higher the transfer efficiency is. As to the load matching factor, the transfer efficiency varies with the load matching factor and is maximized at a particular load matching factor. The optimal load matching factors, related to the transfer distance, are deduced. To verify the conclusions reached above, both the two-coil and four-coil MCR-WPT systems are implemented, and the experimental results are well consistent with the theoretical calculations.

Most sensorless control methods have problems when they are used in surface-mounted permanent magnet synchronous motor (PMSM) that has little salient effect. To solve this problem, a novel low frequency voltage injection method is developed in this paper. Low frequency rotating voltage vectors are imposed on the stator, and the current responses are analyzed to get the rotor position information. Different from high frequency voltage injection, electric torque produced by low frequency voltage would has enough time to move the rotor a little but not big enough to rotate the rotor. The electric torque, friction torque and the cogging torque together will make the rotor oscillate around an equilibrium point. The back electromotive force produced by the rotor movement would have effect in the current response, which is finally used in the rotor position estimation. A rotor position estimation structure based on phase lock loop (PLL) is designed to continuously estimate the rotor position at low speeds and some offline experiments and compensation are added to get more accuracy estimation results. Experiments have been finished on a 1.25 kW PMSM at low speeds and standstill, the correctness of the proposed method has been demonstrated.

Renewable power and storage have made DC based domestic distribution an attractive alternative for future homes. Due to low power rating of the system, it is very important to reduce number of converter stages and use the generated energy efficiently. Therefore, instead of using different dedicated converters from various uni-directional renewable sources, this paper proposes a single stage boost converter with multiple inputs that can efficiently decimate generated energy to charge a battery. This philosophy of interfacing renewable sources will have commercial value when some of the additional sources are not large enough to mandate a dedicated converter. The converter is called Multi-Input-Single Control (MISC) converter. The converter varies the duty cycle based on optimum operation of the largest power source (e.g., MPP in case of solar panel), where as the other smaller unidirectional sources act as slave. As per the characteristic of the source, the proposed converter works under various operating modes which are discussed in this paper. The concept is validated using a laboratory prototype for different operating scenarios with a solar panel as a master source working under MPPT.

A single-switch equalization charger, which is a SEPIC integrated with a series-resonant voltage multiplier, is proposed in this paper. The operation of the SEPIC in the proposed equalization charger is identical to a traditional one, while the series-resonant voltage multiplier is driven by an asymmetrical square voltage wave generated at a switching node in the SEPIC. Most of the total charging power is supplied by the SEPIC, while the series-resonant voltage multiplier provides only a fraction of the charging power to eliminate the voltage imbalance. The proposed single-switch equalization charger not only simplifies the circuitry by reducing the switch count but also the system by combining two components (i.e. a charger and equalizer) into a single unit. An experimental charge-discharge cycling test was performed using a 50-W prototype for four supercapacitor (SC) modules connected in series. The series-connected SCs were mainly charged by the SEPIC while the voltage imbalance was gradually eliminated by the series-resonant voltage multiplier, demonstrating the proposed concept and the equalization performance.

The frequency and voltage droop control is one important method which can deal with power sharing problem and realize “plug and play” function in microgrid. But it is subject to the power coupling and steady-state reactive power sharing error when employed in low voltage microgrids. Furthermore, complex microgrid configurations often make the power sharing more challenging. In this paper, an accurate power sharing strategy has been proposed based on droop control method and communication platform. DG units upload power output information to microgrid control center (MGCC), and receive averaged reactive power instruction from MGCC. The power flows and voltage of microgird will be regulated on line. Finally, the proposed methods will be tested in MATLAB simulation and the results validate the feasibility of them.
