Abstract
As a part of the program we intend to research new topologies of the electrical power converters, that are used in some special technological processes, e.g. welding, laser technology, electroplating. New approaches are foreseen, that can be applied in solid-state converters supplying controlled electrical drives, as well as electronic parameter adaptation of the universal machine. RF disturbances in electronically supplied drives, caused by new materials, high speed and bi-directional operation, will be analyzed and the solutions for their mitigation will be suggested. Specially developed converters would make it possible to separate heavy metals from waste water, produced in galvanization process. Achieved concentration of heavy metals would be for one or even two magnitude orders lower, thus reducing the pollution of environment. In the research of active power filters, a special attention will be paid onto new synchronization methods and symmetrization of the load in three-phase system. Optimal design of electrical machines is possible if accurate electromagnetic field calculation is made. We plan to make special finite elements for calculating fields in the vicinity of singular points and open boundary conditions. We also plan to improve mesh generation algorithm and usage of the computer resources. Optimization of the design of electrical machines with neural networks and genetic algorithms is also explored. New materials and modern technological solutions enable development of electrical machines which meet higher and higher demands of the market. We develop a new three-phase permanent magnet motor. Its advantage is a universal construction and because of this it can be used in applications with a wide spectrum of demands. Fault diagnostic and condition monitoring of electrical machines are becoming very significant in many industrial drives. On the basis of complex mathematical models, the computer simulation of operating characteristics of motor drive are performed. The main purpose of computer simulation is to foresee the changes of motor properties due to the changes of construction parameters as the consequence of different arising faults and damages. Simulation results represent the contribution to the correct evaluation of the measured data and are decisive in the process of developing algorithms and criterion for diagnostics expert systems.
