In the work, simple provisions of the structural synthesis method are used to create new controlled three-phase AC rectifiers with a fractional number of zones. The capabilities of the method are demonstrated by the example of obtaining a simple three-phase two-zone rectifier. The analysis of operating modes indicates the achievement of high energy performance. Calculated expressions setting the relationship between the medium-straightened voltage and the value of the SPD opening angle delay for different zones are obtained. The possibility of rectified voltage smooth regulation relative to the current value of the phase winding voltage is shown: in the first zone from 0 to 2.34, in the intermediate fractional zone from 2.34 to 3.7, in the second zone from 3.7 to 4.68. Due to the intermediate fractional zone, partial overlaps in the specified voltage ranges are allowed.
