High frequency resonant polyphase source for creating high frequency rotary field, has converter provided with phases, where each phase includes switched source that is controlled along time shift corresponding to lags of phases

摘要

The source has a resonant polyphase converter that is associated with parallel phase circuits and provided with parallel phases. Each of the phases includes a high frequency resonant switched source that is controlled along a time shift corresponding to lags of the phases while minimizing homopolar magnitude of the source. Polyphase effect of the source is obtained by switching controls of the converter.
