Morphology
The compound is directly compositional: 'rotary' (operating by rotation) modifies 'converter' (a device that transforms one form into another), so a learner who knows both words can infer it is a device that converts by means of rotation. The detailed technical specifics (AC/DC conversion, synchronous machine) are specialized, but they do not obscure the transparent, predictable combination of the constituents.
Etymology
Rotary converter comes from old machines with big spinning parts that changed one kind of electricity into another. The word rotary points to 'turning' and converter means 'change', so the name fits a device that uses spinning parts to turn AC into DC.
