Industrial frequency multiplier based on a transformer with a rotating field

Abstract

The disadvantage of domestic static converters past generations are the worst dimensions in comparison with rotating converters. Modern inverters use pulse width modulation, which causes problems with electromagnetic compatibility. Imposed by the EU and US sanctions have caused on the agenda of the replacement of imported parts and components, including the search for new ways to develop domestic technology. Known ferromagnetic frequency multipliers have not received applications in industrial energy due to the large mass and low efficiency. Proposed in the article a new method of frequency multiplication solve the above issues, allowing you to implement a simple and reliable converter without the use of imported components. The output voltage of high frequency multiplier is formed by the use of magnetic flux transformer with a rotating field, which has an additional degree of freedom, which is a new solution. Perhaps multiplication with different coefficients of frequency multiplication, including 8 times to provide voltage with a frequency of 400 Hz.
