This study evaluates the power characteristics of a novel permanent magnet flux switching generator (PMFSG) for a low-speed wind turbine. The PMFSG is an outer-rotor type generator. An induced voltage is generated by the change in the magnetic flux flow when the relative position of the teeth changes. The 2-D finite element method (2D-FEM) is used to analyze the PMFSG. The results reveal that the PMFSG generates the large power at the low-speed range and has the low cogging torque. The electrical energy that a PMFSG generates when it is used for a cross-flow type windmill is calculated using wind conditions of three cities. The ratio of the electrical energy generated per hour by the PMFSG to that of a conventional generator is large in places that have the weak winds. This demonstrates that the PMFSG is suitable for the wind power generation in locations where there are weak winds.

This paper describes the design of a digital control for PWM current source rectifiers (CSRs) in the range of 1 – 10MVA. A cascaded control structure is proposed: the inner loop controls the grid currents and the outer loop controls the dc-link current. The proposed grid-current control combines state feedback for active damping of the LC-filter with a servo compensator to increase robustness and guarantee zero steady-state error. It is implemented in the stationary reference frame, which avoids cross coupling as introduced by rotating reference frame transformation. The servo compensator contains a digital resonator and an integrator that eliminates offset currents. It is efficiently implemented as digital filter. The time varying reference for the instantaneous grid current is generated by a disturbance observer for grid voltage. This closed-loop technique inherently compensates the voltage drop across the filter inductance. DC-link current is controlled by a PI-controller. The power factor of the CSR is dynamically adjustable. The proposed control design is verified using a CSR prototype with 11 kVA rated output power. Experimental results are given.

The paper first achieves the real frequency with the power system voltage by using a novel frequency measuring method that is based symmetry principles. Then, it is proposed to obtain the power system current with least square method. At last, the harmonic current is acquired as the load current minus calculated sinusoidal waveform and it is used as the output of an active filter. The numerical simulation shows the new method is effective.

In this paper, a new Punch Through Trench IGBT using a Si(1-x)Gex N+ buffer layer is investigated by using two dimensional finite elements numerical simulations. The performances of this device are mainly obtained from the reduction of the turn-off switching time for a slight elevation of the on-state voltage. A study of the main static characteristics has been performed, particularly the relevance of the trade-off between the turn-off time and the on-state voltage, and its temperature dependency. At least, a comparison with a Carrier Storage Trench-gate Bipolar Transistor and a Trench Field Stop IGBT also including a Si(1-x)Ge(x) N+ buffer layer is done by the mean of trade off curves.

In this paper, a novel current control technique is proposed to control both the active and reactive power of a single phase hybrid PV inverter connected to grid. The hybrid PV inverter not only maintains constant load voltage but also ensures active and reactive power flow from the grid with low THD even at the presence of non-linear load. A p-q theory based approach is used to find out the current reference of the parallel converter to ensure desired operating condition at the grid terminal. A novel current controller is also proposed. The proposed current controller is very simple to implement and gives superior performance over the conventional current controller such as rotating frame PI controller. The stability of the proposed controller is ensured by direct Lyapunov method. Detailed simulation as well as experimental results are presented to show the efficacy of the proposed current control scheme along with the proposed Non-Linear controller.

A planar magnetic is a low profile transformer or inductor utilizing planar windings instead of the traditional windings made of Cu-wires. In this paper, the important factors for planar transformer design including winding loss, core loss, leakage inductance and stray capacitance have been investigated individually. The tradeoffs among these factors have to be analyzed in order to achieve optimal parameters. Combined with a certain application, four typical winding arrangements have been compared to illustrate each their advantages and disadvantages. An improved interleaving structure with optimal behaviors is proposed, which constructs the top layer paralleling with the bottom layer and then in series with the other turns of the primary so that a lower magneto motive force (MMF) ratio m can be obtained as well as minimized AC resistance, leakage inductance and even stray capacitance. A 1.2-kW full-bridge DC-DC converter prototype employing the improved planar transformer structure has been constructed, over 96% efficiency is achieved and a 2.7% improvement compared to the non-interleaving structure is obtained.

Future electric vehicles (EVs) will be linked to the electric power system infrastructure; the vehicles will operate through frequent electric charging, as is the case with electric trains. Conventional batteries require a long recharging time; therefore, supercapacitors, rather than batteries, will play an important role in the future for charging of EVs. Recently, we manufactured small EVs powered only by supercapacitors. Supercapacitors have a long operating life, large current density, and environmentally friendly composition. Further, their energy level can be estimated from their terminal voltage. Because EVs powered by supercapacitors can operate for more than 20 min after being charged for only 30 s, the requirement for constant recharging of EVs is reduced substantially, thereby increasing the efficiency of these EVs. Wireless power transfer based on magnetic resonance is an extremely important technique that needs to be considered for enhancing the efficiency of EVs. In a laboratory experiment, this technique enabled approximately 50 W power transfer with more than 95% efficiency at a distance of more than 50 cm. In order to improve energy efficiency and safety of future EVs, the implementation of novel motion control techniques for EVs is required. Since EVs are powered by electric motors, they have three major advantages: motor torque generation is quick and accurate, a motor can be attached to each wheel, and motor torque can be estimated precisely. These advantages enable the realization of highperformance antilock braking and traction control systems, control of two-dimensional chassis motion, and estimation of road surface condition. In summary, we can achieve a large-scale development of future vehicles that employ three techniques: Electric Motors, Supercapacitors, and Wireless Power Transfer. This eliminates the requirement for engines, high performance Li-ion batteries, and large charging stations.

This paper proposes a new half-bridge inverter based active power quality compensator (APQC) for electrified railways with a three-leg inverter. The first-leg is connected to α-phase, and the second-leg is connected to β-phase. The midpoint of two capacitors on the dc side is connected to the ground line. These two half-bridge inverters exchange the active power on the each feeder each other through two dc capacitors, and compensate the negative-sequence and harmonic components of the load currents. The third-leg performs a dc voltage balancer for two dc capacitors connected to the half-bridge inverters. Thus the balanced and sinusoidal source voltages and currents factor are attained on the primary side of the Scott transformer with the balanced dc capacitor voltages. The basic principle of the proposed half-bridge inverter based APQC is discussed in detail, and then confirmed by digital computer simulation using PSIM software. Simulation results demonstrate that the balanced source currents with the unity power factor are obtained on the primary side the Scott transformer in the traction substation systems balancing two dc capacitor voltages.

In this paper a novel online simulator is introduced that is integrated into the educational project iPES which is a free collection of Java applets for educational purpose. iPES has been translated into 12 languages and has currently more than 10, 000 visits per month. The novel online simulator is optimized for power electronics, easy to use, and allows unlimited simulation of converter topologies. The concept of embedding a circuit simulator in the form of a Java applet into a webpage allows the creation of power electronic and electrical engineering courses that are easy for students to access, highly flexible and require a low administrative effort. The paper will discuss the status of the iPES project in detail including all shortcomings and will show how the integration of the online simulator significantly improves the educational value.
