FIELD: electricity.
SUBSTANCE: invention relates to the field of electric engineering and may be used in converters within a power supply system of electronic, electromechanical and lighting equipment. In the method of power ratio corrector control during the interval of positive half-wave of the supply voltage of the grid the first power key is maintained in the connected condition, and control pulses arrive to the second power key. During the interval of the negative half-wave of the supply voltage of the grid the second power key is maintained in the connected condition, and control pulses arrive to the first power key, at the same time the inlet voltage is measured by the control system based on the digital signal processor with the help of two half-wave rectifiers with identical division ratios.
EFFECT: increased efficiency of energy conversion and accuracy of operation of a single-phase bridgeless corrector of power ratio.
