In this paper, the design strategies of inverter-driven induction machines are discussed. This is followed by a description of a computer aided design and analysis package specifically for this purpose. The program package permits integration design of machines with inverters, comprehensive performance analysis, and system optimization, resulting in 20-30% more power density for the induction machine than that designed for direct utility power supplies by conventional methods. Design and performance analysis results are presented to substantiate the conclusions.","PeriodicalId":117576,"journal":{"name":"IAS '95.

The high voltage, short pulses achieve adequate charge-to-mass ratios, while reducing the total ionic current landing on the dust layer and thus minimizing the deleterious back corona effects. To throw further light on this corona charging process, which up to the present has not been put to wide use by the electrostatic painting industry, the authors present a preliminary experimental study applied to powder coating. Measurements are presented for the Q/M ratios of the charged powder fractions collected in an ensemble of 5 double Faraday pails mounted in a cross behind the target plane. The results indicate, on average, a substantial increase in the charge-to-mass ratio of powder, combined with a reduction of the total ionic current which bombards the painting target.","PeriodicalId":117576,"journal":{"name":"IAS '95.

In this paper expressions are derived to obtain maximum torque for both stator and rotor flux FOC with a nonlinear motor model. On the one hand it is shown that the expressions for nonlinear rotor flux FOC are only slightly more complex than for the linear case, while nonlinear stator flux FOC yields significantly more complex equations. On the other hand the equations for rotor flux FOC in the field weakening region are only slightly more complicated than those for the stator flux system. However, for rotor flux FOC, a fair approximation can be derived, which is easy to use.","PeriodicalId":117576,"journal":{"name":"IAS '95.

This paper investigates modern soft-starters for induction motors at three different power levels (3 kW, 7.5 kW and 22 kW). The investigation includes efficiency measurements, start-up measurements and measurement of the grid current harmonics at different loads to investigate the soft-starters performance against new regulations. The measurements are compared with an induction motor without soft-starters. It is concluded soft-starters have energy saving capabilities at low load up to 4% of rated power for small motors, but it is also concluded the payback time will be long. Finally, it is concluded soft-starters have problems with new grid disturbance regulations at low load operation.","PeriodicalId":117576,"journal":{"name":"IAS '95.

These disadvantages of the passive power filter can be improved by the combined use of active and passive power filters and by appropriately coordinating their operations. To harmonics generated by the nonlinear load, the varying frequency components are compensated by the active power filter and the fixed frequency components by the passive power filters of the proposed method. This provides a good harmonic compensation over the entire operation range for the irregularly varying frequency harmonic current generated by the nonlinear load. In addition, this arrangement suppresses parallel and series resonances. In this paper, an operation and control strategy for the proposed hybrid power filter is analyzed and simulated.","PeriodicalId":117576,"journal":{"name":"IAS '95.

For a six pulse diode rectifier system it is shown that voltage unbalance and pre-existing voltage distortion in the utility generates uncharacteristic harmonics in the line currents. The amplitude of these uncharacteristic harmonics are shown to be amplified if the diode rectifier is operating in discontinuous conduction mode. For a twelve pulse diode rectifier system connected in parallel to feed a common DC link via interphase reactor it is shown that a small amount of impedance mismatch, utility voltage unbalance or pre-existing voltage distortion drastically affects the current sharing capability of the rectifier bridges. This in turn generates additional uncharacteristic and characteristic harmonics thereby increasing the THD. In order to mitigate these effects and ensure proper operation of diode rectifiers, specially designed line reactors termed as harmonic blocking reactors (HBRs) are introduced The analysis and design procedure for the HBRs are discussed. Simulation results illustrate improved performance. Experimental results from a laboratory prototype system show close agreement with theory.","PeriodicalId":117576,"journal":{"name":"IAS '95.

To maintain minimum volume and weight of the power supply unit on board the transportation vehicle, peak thrust per unit current operation is a desirable objective. True peak thrust per unit current through slip control is difficult to achieve because the parameters of linear induction machines vary during normal operation. This paper first develops a peak thrust per unit current control law based on the per-phase equivalent circuit for linear induction machines. The algorithm for identification of the variable parameters in induction machines is then presented. Application to an operational linear induction machine (LIM) demonstrates the utility of this algorithm. The control strategy is then simulated, based on an operational transit LIM, to show the capability of achieving true peak thrust operation for linear induction machines.","PeriodicalId":117576,"journal":{"name":"IAS '95.

The simple construction and low cost of the SRM have made it an attractive candidate for replacing adjustable speed drives in automobile, aerospace, manufacturing and consumer product. Smooth operation and control of the SRM greatly depend on the external control unit. Instead of using a traditional digital controller with discrete devices, the authors have designed and fabricated a single chip logic controller for controlling torque and speed of an SRM. They have used a programmable logic device (PLD) to implement the digital logic coupled with a power controller. They have described the operational logic in the form of a block diagram and from there have derived the controller logic. Initial testing of the controller for a four-phase SRM drive has been completed. Thorough testing and further research are in progress.","PeriodicalId":117576,"journal":{"name":"IAS '95.
