Abstract
We consider the use of the sectoral method of regulation to improve the power factor of the band converters. Produced by Fourier analysis of the current curve to confirm the theoretical data.The calculation of the proportion of reactive power levels and higher harmonics defined shift and distortion coefficients for sector regulation method.Evaluated the effectiveness of sectoral regulation as a way to improve the power factor of the four-rectifier with a ladder structure for electric alternating current.
Keywords: power factor, sectorial regulatory, distortion factor
