To meet the system requirements and physical constraints, the actuator was designed using the high energy density magnets, MAGNEQUENCH-3 (MQ3). The magnetic circuit of the actuator was modeled using finite element-based magnetic field analysis. The actuator was built and tested and the results confirmed the predicted performance. Because of the presently high cost of MQ3 magnets, a parametric study was then conducted to determine possible design trade-offs and the impact of using ferrite magnet material on actuator size and performance.","PeriodicalId":117576,"journal":{"name":"IAS '95.

Worldwide about 50 million motors are installed every year which are greater than 1/2 hp. Three-phase induction motors are very simple and inexpensive to build. An AC motor may be used for variable speed applications with the addition of an AC inverter. An accurate model of semiconductor power losses is necessary to design a reliable invertor system using a minimum amount of silicon. Equations for the average and RMS transistor and diode currents are derived based on a quantitative analysis of the current waveforms. Conduction losses in the semiconductor devices are then approximated using a piecewise linear approximation of the device's on-voltage characteristics. Measurements of switching energy versus current are used to obtain a curve of losses versus current. Integration of these losses over a full sine wave period is used to obtain a closed form expression for switching losses as a function of sine wave current. Total losses, conduction losses and switching losses are compared to thermal measurements. The model is further tested by comparing predicted and actual losses at different PWM frequencies.","PeriodicalId":117576,"journal":{"name":"IAS '95.

Through this approach it is possible to obtain low-distorted and in-phase line current without the need for sophisticated mathematical analysis or complex models to design the controller. Moreover, the intrinsic nonlinearity of this control technique allows improved dynamic response and increased robustness as compared to linear approaches. In the paper, controller design and operation are discussed, and implementation by a microcontroller is described. Actual power converter operation is analyzed by simulation in the case of a boost PFP, demonstrating the feasibility of the approach.","PeriodicalId":117576,"journal":{"name":"IAS '95.

A new theoretical analysis of the interaction between harmonic field components due to static and dynamic rotor eccentricity which previous research has not considered is put forward. The resultant harmonic current components produced in the supply current which are highlighted by the analysis are found to exist experimentally and indeed shown to be a function of the combined effect of both dynamic and static eccentricity. Further vibration analysis is put forward to identify which particular form of rotor eccentricity is dominant; hence illustrating how faults can be identified in a motor using condition monitoring techniques.","PeriodicalId":117576,"journal":{"name":"IAS '95.

In the robotic one side MIG welding process without a backing plate, in order to obtain a good quality of weld, it is important to control the weld pool shape so as to prevent the melting metal from burning through the plate. The method of controlling the weld pool shape is discussed. The moving torch is repeatedly switch changed, known as the switch back method. Primary welding experimental results have proved that the switch back method is effective and satisfactory for controlling the back weld pool shape in one side MIG welding processes without a backing plate.","PeriodicalId":117576,"journal":{"name":"IAS '95.

With the increasing integration scale of static power converters, power electronic components are located very close to signal components. Moreover, circuits are increasingly implanted on the same substrate. During the commutation of the semiconductors, high voltage rates appear to the power transistor, creating common mode currents which return through control elements and may disturb them. These common mode currents are generated by parasitic capacitances existing between ground-plane and circuit traces. Simulations can be used to characterize this kind of perturbation, but many simulations are needed before finding the good design of traces. A new approach is proposed to model the disturbance process in order to optimize the traces of circuits. This approach establishes a guide for technological design of the circuit without modifying the function of the system. A practical case is studied that allows the proposed design rules to be applied.","PeriodicalId":117576,"journal":{"name":"IAS '95.
