The thyristor switches play the role of protecting power generating facilities against voltage dip and interruption. In order to make the overall unit compact, thyristor switches are installed in only two phases by eliminating a switch of one phase out of three. A DC-converted voltage signal without ripple is employed to detect voltage drop quickly. The performance of the system is confirmed checked by generator combination tests.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

At first, the analytical expressions for the total harmonics of the inductor current and capacitor voltage of the LC filter are derived. As the unique values of the parameters of the LC filter cannot be specified based on the total harmonic of the capacitor voltage alone an additional criterion based on the minimum reactive power of the LC filter is used to specify these parameters. Experimental results are included to verify the derived expressions.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

Modern digital control techniques such as software generated pulse width modulation (PWM) and phase locked loop (PLL) realized in software, will be employed. With the use of an advanced single chip microcontroller (MCU) digital and analog circuit design could be reduced to a minimum. The power part is realized as a three phase bridge structure (B6) with six IGBTs with a switching frequency of 15.625 kHz. Due to the duality of the power structure, it is possible to realize both energy directions. The study contains mathematical analysis and simulation, and as a result to these studies a description of a prototype with about 15 kW.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

The method could be used for the motor design optimization and refinement in the drive control strategies aiming at better performance of the drive. In this paper the method of magnetic equivalent circuit (MEC) has been modified to account for high local saturation in the pole tips and to model the field gradient in the airgap more accurately. Significant accuracy improvement has been gained compared with the conventional MEC method. The model is simple and computational time is low. The model has been used for prediction of SR motor characteristics.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

The assessment is based exclusively on measured terminal voltages and currents. Low cost, medium performance sensorless drives can be designed using simple algebraic speed estimators. High-performance systems rely on dynamic models for the estimation of the magnitude and spatial orientation of magnetic flux waves in the stator or in the rotor. Open loop estimators and closed loop observers differ with respect to accuracy, robustness, and limits of applicability. The overview in this paper uses signal flow graphs of complex space vector quantities to give an insightful description of the physical and mathematical systems used in sensorless control.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

However, the LISN measures only the total contribution of common-mode (CM) and differential-mode (DM) emissions in the live or neutral line. In EMI filter design, it is always desirable to be able to determine whether the differential- or the common-mode component is dominant in order to pin-point the effective element of the filter to be changed to reduce the total emission. This, in essence, minimizes the trial-and-error guess work in selecting the proper components of the filter and cuts down on design time. This paper touches on the conventional way for measuring total conducted noise emissions of a product and how the CM/DM discrimination network (CM/DM DN) can be used as an effective diagnostic tool for the modification of power supply filters to reduce conducted noise emissions.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.

This paper presents a new approach for modelling the motor for torque analysis and control. This method is unconventional in that no parametric model of the motor is required; instead a new concept of 'motor identity' is introduced and used. This 'identity' is defined as the per-phase torque profile of the motor and it can be represented in a matrix form-called the 'identity matrix'. This characterizes the motor and this matrix can be used for torque analysis and control. This concept is also applicable to all synchronous machines but a PMSM is used here for the illustration of this concept. An analysis is also presented for deriving optimal drive currents by using the motor identity. A method to extract the motor identity experimentally is also given in this paper.<<ETX>>","PeriodicalId":244042,"journal":{"name":"Proceedings of 1995 International Conference on Power Electronics and Drive Systems.
