synchronous converter

When used in this way it is referred to as a synchronous rotary converter or simply a synchronous converter.

Another advantage of the synchronous converter is that it is bi-directional, which lends itself to applications requiring regenerative braking.

In 1917, the PRR installed two 11 kV, 4.5 MVA synchronous converters at Radnor, the approximate center point of the system load.

A later development is the synchronous converter, in which the motor and generator windings are combined into one armature, with slip rings at one end and a commutator at the other and only one field frame.

With an M-G set, the DC can be considered to be separately generated from the AC; with a synchronous converter, in a certain sense it can be considered to be "mechanically rectified AC".
