synchronous converter การใช้

• 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.
• 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 ".
• Early AC-to-DC converters used an induction or synchronous AC motor direct-connected to a generator ( dynamo ) so that the generator's commutator reversed its connections at exactly the right moments to produce DC . 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.
