Abstract
In a 12-pulse AC/DC converter of the hexagon type the rectifier switches are distributed in three groups for each polarity and for each polarity three coils are joined to the common pole and connected separately to the pairs of rectifier switches of a corresponding group. As a result, the capability of the hexagon is extended to commutation of diodes, instead of controlled rectifier switches, by the effect of such interposed commutation inductance.
