To help quantify and optimize assertion, the improvement in performance resulting from utilization of the third harmonic voltage is the topic of this paper. Two different topologies are studied; series rectification (SRS) and polyphase rectification. It is shown that, for a constant value of peak flux density, a maximum power gain of 15.5%, with respect to the pure sinusoidal case, can be obtained and that this gain is primarily a result of an increase in fundamental volts. The presence of a third harmonic in the flux density distribution yields higher core losses. For a constant peak flux density the hysteresis loss remains constant and the eddy current loss increases. However, the net increase in output power offsets the increment in core losses and a higher efficiency is achieved. The analytical predictions are compared to simulation results and experimental measurements for the three phase case. For the experimental set-up, having a third harmonic voltage of 20%, the overall efficiency is estimated to have increased by nearly 1% when compared to the pure sinusoidal case.","PeriodicalId":177291,"journal":{"name":"IAS '96.

As part of this program, advanced machine navigation and control technologies are being developed for underground room-and-pillar and highwall coal mining that can be applied to commercially available mining equipment. These technologies use off-the-shelf components and a flexible control software architecture to minimize the effort required to adapt them to mining equipment. An accurate reliable navigation system that can provide the mining machine's heading and location at all times is a critical requirement for a remote-controlled mining system. After much research involving several different types of navigation sensors, the Honeywell Ring Laser Gyro Inertial Navigation System was selected as showing the most promise. It has been installed on a continuous mining machine at PRCs surface test facility. This paper describes the system being employed on a mining machine while final accuracy and performance testing continues.","PeriodicalId":177291,"journal":{"name":"IAS '96.

Designers do not have the confidence to totally eliminate the hardware breadboarding steps for at least two reasons. One is that discrete electronic component models as well as fluorescent lamp models either do not exist or are not sufficiently accurate. The second is that many iterations of computer simulation are generally required to match the resistive lamp impedance curve when detailed lamp models don't exist and resistive lamp models are used. However, with the development of new integrated circuits designed specifically for fluorescent electronic ballasts, the lamp and non-IC component models become less important, especially if the IC controller operates at a fixed frequency and if certain network criteria are met. As a result, the extensive hardware breadboarding phase can be drastically reduced. One design example is presented and summary results are tabulated. Some key waveforms from simulation and measurement are compared. Then, the design is expanded to the entire family, the circuit parameters of which are calculated.","PeriodicalId":177291,"journal":{"name":"IAS '96.

The ISTAC is a technique where the magnetic flux density around the fixed contact in an arc chamber is enhanced using a new fixed conductor which is formed in a J-shape. This increases the arc driving force and the opening torque of the movable conductor at the beginning of the current-breaking motion. During this development, the magnetic fields in arc chambers were analyzed by 3-dimensional nonlinear numerical analysis and the usefulness of the analysis was confirmed by measurement. A new arc chamber configuration was designed and optimized using this analysis. It became clear that at the beginning of the current-breaking motion the magnetic arc driving force and the opening torque of the movable conductor in the new arc chamber with the J-shaped conductor were larger than those in old arc chambers with a U-shaped fixed conductor. In a high current-breaking test, an experimental MCCB with the new arc chamber showed 1.6 times the rising rate of arc voltage of the old one. By use of the ISTAC, a new type of MCCB has been developed, having a high level of current limiting performance in spite of its small external dimensions. Moreover, free spaces in the MCCB due to the reduction in size of the arc chamber could be used for supplementary functions.","PeriodicalId":177291,"journal":{"name":"IAS '96.
