Static synchronous compensator (STATCOM) based on three-level neutral point clamped (NPC) converter is presented. A simple equivalent circuit of three-level converter is analyzed to predict the deviation of node voltages, and the capacitor voltage imbalance mechanism of three-level NPC converter is analyzed. An optimization algorithm of space vector pulse width modulation ( SVPWM ) for capacitor voltage balance of three-level NPC converter is presented.

A novel direct torque control based on terminal sliding mode controller for doubly salient electro-magnetic machine was proposed in this paper. The mathematical model of the motor has been constructed and generation principle of torque ripple was analyzed. Based on analysis of torque ripple, phase current waveforms had been optimized to reduce the electro-magnetic torque ripple by using direct torque control strategy. Meanwhile, torque observer was built to calculate output torque of the machine in real time and terminal sliding mode controller was applied in speed regulating loop to improve dynamic response. Moreover, the stability characteristic of terminal sliding mode controller was proofed by Lyapunov function. Finally, a field-circuit co-simulation model was built and some simulation results verify the feasibility of control strategy and theory analysis.

A speed and flux estimation method of induction motors using fuzzy extended kalman filter(FEKF) is proposed in this paper, which is used to make lower impact of time varied statistic of measurement noise. It reaches a better speed estimation accuracy of induction motors than the extended kalman filter(EKF). The proposed algorithm modifies the measurement noise covariance of extended kalman filter recursively by monitoring if the ratio between filter's innovation and actual innovation is near 1, and chooses a fuzzy factor to make its noise model close to real noise model adaptively. The speed estimated error and the flux fluctuation of FEKF under gross external disturbance and unknown measurement noises are compared with EKF. Simulation and experimental results show that FEKF provides better performance and faster convergence than EKF under gross external error and unknown measurement noises.

Magnetic flux leakage transformer (MFLT) is widely used in the stable power supply of electronic equipment. For MFLT, whose characteristics become more complex and nonlinear for its leakage and load, the traditional circuit analysis method of transformer could not describe it accurately. In this paper, a nonlinear-transient field-circuit coupled finite element model is used to simulate the MFLT with special magnetron load. The steady and dynamic performances of the whole system were obtained based on the full consideration of the MFLT's complex magnetic field, special power supply circuit and load characteristics. The simulation results were consistent with the experiments, indicating the correctness of the proposed simulation model. This method can be used to analyze MFLT working states and optimize the power supply system scientifically, accurately, effectively and rapidly.

Conventional Wireless Power Transfer (WPT) has limitation due to the contradiction between the power transfer efficiency (PTE) and power transmission distance. A novel network called Wireless Power Transfer Network (WPTN) is proposed to help overcome the limitation, and power is efficiently transferred from a transfer node to a receive node via relay nodes over a relatively long transmission distance. A novel power transfer routing optimization method for WPTN system based on the Cross Entropy (CE) method is proposed. Furthermore, an electrical load is seen as a power node in WPTN system, which has three operating status and are described in detail. In addition, a single power transfer route PTE mathematic model is built, and the correlation between the number of nodes, frequency and the PTE are analyzed also. Furthermore, a WPTN system with ten nodes is taken as an example, the most optimal route is selected based on the CE method according to the PTE and constraint conditions. Finally, simulation results verifies the effectiveness of the proposed method, the PTE achieves an efficiency of 56.01% compared to 0.25% from a conventional two-node system.
由于功率传输效率(PTE)与功率传输距离之间的矛盾，传统的无线功率传输(WPT)存在一定的局限性。为了克服这一限制，提出了一种新的无线电力传输网络(Wireless Power Transfer network, WPTN)，电力通过中继节点在较长的传输距离上有效地从传输节点传输到接收节点。提出了一种基于交叉熵法的WPTN系统输电路径优化方法。此外，将负载视为WPTN系统中的一个功率节点，并对其三种运行状态进行了详细描述。建立了单功率传输路径PTE数学模型，分析了节点数、频率与PTE之间的关系。以一个有10个节点的WPTN系统为例，根据PTE和约束条件，基于CE方法选择最优路由。最后，仿真结果验证了该方法的有效性，与传统双节点系统的0.25%相比，PTE的效率达到56.01%。

In order to reduce the harmonics in input currents effectively, this paper presents a double star rectifier with an auxiliary PWM rectifier at DC side. The volt-ampere rating of auxiliary PWM rectifier is only 10% of output power of the double star rectifier. The auxiliary PWM rectifier injects a particular triangular wave current into the secondary winding of inter-phase transformer to reduce the THD of input currents. The resulting system draws near sinusoidal utility line currents with less than 5 % THD. The auxiliary PWM rectifier also extracts the harmonic energy and feeds to the load. Detailed analysis of the proposed scheme is presented, and the results of experiment verify the analysis.

This paper introduces a digital multi-mode boost converter with wide range of input voltage for an energy recycling load system. The boost converter is controlled digitally with constant off- time/constant frequency hybrid pulse width modulation (PWM) control. Constant off-time control is to avoid the limit cycle oscillation and gain a high gain when the input voltage is far less than the output voltage. Otherwise, constant frequency PWM is adopted. Finally, A 3.6kW DC/DC boost converter with twelve 300W channels in parallel was built for an energy recycling load system and the experimental results testify it to get high gain up to 49 and high efficiency up to about 98%.

In modern smart electric grids, power cables are supervised by a large number of monitor equipments. In many field application cases, current transformers (CT) are employed to extract electrical power from these high voltage cables to supply monitoring circuits. In this paper, in order to harvest maximum power from cables, key parameters of the rectifier with current transformer circuits are analyzed, and the design considerations are discussed. A high frequency PWM control scheme is proposed to regulate the output voltage by regulating the current circulation duty ratio. Theory analysis and simulation are given. Experiments based on a 20W prototype verify the validity of the proposed methods.

The collective dynamics under different coupled strengths in the coupled synchronous reluctance motor drives is presented in this paper. With variation of the coupled strengths, the coupled system exhibits rich dynamical phenomena such as amplitude death, periodic anti-synchronization and complete synchronization. By the amplitude death the coupled synchronous reluctance motor drives can be stabilized into the equilibrium. The attracting regimes of the coupled system are studied. The attracting behaviors with different initial conditions are analyzed. Due to the coexistence of multiple attractors, the coupled system can be controlled to different fixed points under different initial conditions. The multiplicity of the operation of the coupled system is enriched. The secure operation of the coupled drives can also be maintained.

This study presents a novel topology named high voltage-gain boost DC-DC converter with tapped-inductor. The proposed topology provides a high voltage-gain and low input current ripple which are suitable for alternative power sources such as PV and fuel-cell applications. The interleaved control mode can be used to reduce input and output filtering. Moreover, the voltage stress on MOSFETs are clamped, resulting of low on-resistance (RDS(ON)) MOSFET usage to improve efficiency. Addition to providing circuit operation and analysis with symmetric control and interleaved control modes, a simulation and laboratory prototype of the proposed topology was built and inspected under 15-28 V input, 400 V/250 W output and 100 kHz switching frequency. The results showed that the proposed circuit achieved low voltage spikes on MOSFETs. Low RDS(ON) MOSFETs were used to improved efficiency. For interleaved control mode, the input current ripple and output voltage ripple were low, requiring smaller input and output filtering.
