Table Voltage and Current Relations
The following points are north nothing :
Conversion from 3-phase to 6-phase can be easily achieved by having two similar secondary windings for each of the primary of the three-phase transformers. There are many ways of connecting the six secondaries for this purpose such as
(i) Diametral (ii) Double-delta (iii) Double-star.
The output D.C. voltage of rotary converter can be changed by the following methods :
(i) By using tap-changing transformer
(ii) By reactance control method
(iii) By induction regulator method
(iv) By synchronous booster control method.
