Abstract:

The frequency converter schemes for power supply systems of the variable speed motors with permanent magnets are overviewed in the paper. Mostly the schemes of the autonomic current inverters with the artificial phase current switching are analyzed. The different aspects of the current switching process depending of the scheme topology are studied. The recommendations to choose the real scheme of the frequency converter were elaborated.
