A direct rotor field oriented control (DRFOC) of a dual-three phase induction motor drive is described in this paper. The induction machine has two sets of stator three-phase windings spatially shifted by 30 electrical degrees. The stator windings are fed by a current controlled PWM (CRPWM) six-phase voltage source inverter (VSI). Three key issues are discussed: (1) the machine dynamic model is based on the vector space decomposition theory; (2) the PWM strategy uses the double zero-sequence injection modulation technique which gives good results with low computational and hardware requirements; and (3) to eliminate the inherent asymmetries of the drive power section, a new current control scheme is proposed. Experimental results are presented for a 10 kW dual three-phase induction motor drive prototype.

Newly fabricated junction field effect transistors (JFETs) and high electron mobility transistors (HEMTs) based on gallium nitride (GaN) substrates are presented. The devices, grown with plasma assisted molecular beam epitaxy (PAMBE), are to be used for power switching applications. Very high quality p- and n-type films were grown. Some test results are shown for surface smoothness and for successfully processed Schottky diodes.

The tandem rolling of metal is a complex engineering process whose optimization represents a challenging control problem. The current technology relies on complex nonlinear models that are used to develop control strategies to address the various control problems encountered. Such models however, necessitate extensive computational requirements for simulation. Also, in various instances, access to the detailed models may be unavailable, or computational capability may be limited, yet it is desired to obtain some rough indication of performance of specific control systems when coupled to the mill. Thus the need arises for a simplified model (which can be easily implemented on a PC) for testing of control concepts. This paper fulfills such a need by providing a simple linearized model of the mill. An example of the usefulness of the model is presented by coupling to a linear quadratic optimal controller with a simple method to mitigate disturbances in incoming metal thickness. Satisfactory results are demonstrated by a simulation.

The authors present a method allowing evaluation of the mechanical performances (torque, speed, mechanical power, dissipated losses on the surface of contact between stator and rotor) of travelling wave ultrasonic motors. The visualization of the motor characteristics makes it possible for the manufacturer to optimize the operation point of the motor compared to the commonly used criteria. The method was developed based only on a 2-D equivalent mechanical model of the motor.

The proposed noninvasive method of measurement of the charge level on a population of particles employs the phase Doppler anemometry (PDA) technique in conjunction with a high-resolution computer controlled traversing system. The PDA system was used to track the motion of charged particles in the presence of a DC electric field. By solving the equation of a particle motion in a viscous medium combined with the simultaneous measurement of its size and velocity the magnitude as well as the polarity of the particle charge can be resolved. In order to detect particles with high electrical mobility and to cover the wide range of electrostatic charges the probe volume was moved mapping the velocity of the particles within the space between the parallel plate electrodes. The preliminary experimental tests were carried out on dioctyl phthalate aerosol droplets produced by nebulising isopropanolic solutions using a Medic-Aid Sidestream nebuliser. The experimental results show that inherent electrostatic charge on dioctyl-phthalate droplets ranged from -250 to 250 electrons with an average charge-to-mass ratio of 0.24/spl mu/C/g. In case of precharged aerosol the average charge-to-mass ratio increased to 20/spl mu/C/g. The results presented demonstrate capability of the technique to allow real-time determination of particle size and charge with a high particle count rate in order of several thousands particles per second.

A design procedure for the consequent pole permanent magnet (CPPM) machine is presented. Due to its double excitation nature (PM and field winding) and inherent three-dimensional flux distribution, an appropriate set of equations must be derived to model its magnetic structure. For practical operating conditions, radial, axial and tangential flux components are present. Therefore a convenient representation of the magnetic sources and their magnetic paths are necessary. For this purpose, a simplified reluctance-based equivalent circuit for 2-poles is developed to capture the main features of the machine. Approximated expressions for the airgap flux and the airgap flux density are derived. In these expressions the constant contribution of the PM and the variable flux provided by the field winding are taken into account. In addition, a formulation to calculate AC and DC slot geometry, copper and iron losses estimation and output power are developed. Finally, an optimization procedure is outlined based on maximum material utilization under current and magnetic loading constraints.

The paper deals with a new disk type PM brushless motor consisting of only stator (armature) winding and permanent magnet (PM) excitation system. No stator and rotor ferromagnetic cores have been used. To obtain the required value of the magnetic flux density in the air gap, PMs have been arranged in the so called "Halbach array". The FEM analysis has been done to prove that in a double sided motor with internal stator (twin PM rotor embracing a coreless stator), the peak value of the magnetic flux density can exceed 0.6 T. This is a sufficient value to design a high power density machine. A low speed 10 kW motor has approximately 1% higher efficiency and provides 82% more output power per kilogram than its cylindrical counterpart with a ferromagnetic core.

This paper presents analytical tools aimed at improving and simplifying the development of frequency-controlled dimming electronic ballasts. A modified phasor transformation is proposed that converts a frequency-modulated signal into an equivalent time-varying phasor. The proposed transformation is applied to develop a complete small-signal phasor model of the LCC resonant ballast, which explicitly models the effect of the frequency modulation on the envelopes of the outputs. A Spice-compatible implementation of the model is presented that facilitates AC analysis of the ballast in addition to envelope transient simulation, and is verified through comparison of experimental and simulation results. A closed-form solution of the control-to-output current transfer function for the ballast-resistor system is presented, along with key observations of the pole locations and low-frequency gain that facilitate simple and intuitive compensator design. Finally a design example for the feedback controller is given to verify the theoretical analysis.

Planar integrated L-L-C-T (inductor-inductor-capacitor-transformer) technology has been the subject of intensive research over the last few years. Research of modeling and explaining its behavior in different power electronic circuits has been conducted. However, most of the previous models are based on first order approximation. High frequency characteristics of L-L-C-T cannot be modeled by those models. A second order approximation lumped parameter equivalent circuit of L-L-C-T is proposed in this paper. This model can describe the characteristics of L-L-C-T up to the third resonant frequency. The parameters of the model can be either extracted from small signal measurement or calculated from the L-L-C-T geometry structure. The proposed model is used to analyze the secondary voltage ringing of an asymmetrical half-bridge converter (AHBC) in distributed power system (DPS) applications. The predicted result matches the measurement result well.

In this paper, the transient analysis and design of a current pulse generator for a rail gun is presented. In this paper, the ringing effect is investigated. Based on the half-bridge circuit, the possible switching pattern causing the ringing effect is verified thoroughly. A high frequency switching model is derived for the linear rail gun. The equivalent circuit model is also derived to analyze the ringing effect further. An FPGA digital implementation for the current pulse control is also concentrated upon to obtain precise timing control for the current pulse generator. By simulation and experimentation, it shows that the ringing phenomena can be observed by way of this developed model. The current pulse is generated successfully with the digital implementation. It is believed that the associated investigation is useful to improve the performance for the linear rail gun.
