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.
