The paper presents a refined method of calculation of the static characteristics of asynchronous generator at work on dynamic active-inductive load, adjusting the frequency of generated voltage. Found that the neglect of changes in the function of the frequency of the voltage load of low-power results in significant inaccuracies in determining the boundaries of stable operation. Based on experimental studies proved the adequacy of the proposed method.

An approach to the creation of a discrete controller as artificial feedforward neural network, which consisting of three single neurons with linear activation function is outlined. Control setting is in accordance with the training of the neural network algorithm, based on the analysis of the quality criterion. Development can be adapted to the control of the power converter, the engine. Software developed on environment LabView 8.X. It visualizes the control process, analyzing the control quality and is used in the learning process.

Кey words: neural network, optimization.

The authors have substantiated the urgency of assessment of electromagnetic impact of the electromechanical energy converters on biological objects. The article is focused on the AC electric drives equipped with induction motors, which are the load of the semiconductor PWM-controlled energy converters supplying. The experimental research results, obtained by the authors, are presented for the magnetic field intensity around the induction motors that are supplied by the PWM-controlled frequency converters with the supply asymmetry. The first attempt was made to determine the maximum permissible level of electromagnetic radiation, which is the teratogen, e.g. mutagen, for the Drosophila melanogaster biological test-objects.

Key words: energy conversion, AC electric drive, electromagnetic radiation, maximum permissible level, bioassay, test-objects, teratogenesis, mutations.
