The Static Converter as Power Actuator for DC Drives
A characteristic feature of the rotating converter discussed in Sect. 7.4 is the consecutive power conversion from electrical (constant AC line voltage) to mechanical (speed of motor-generator) and back to electrical form (variable direct voltage) from which it is eventually transformed into controlled mechanical power in the drive motor. These conversions constitute the advantages of the control scheme (separate electrical circuits, decoupling by rotating masses) as well as its drawbacks (cost of machines, foundations, power losses, servicing, limited speed of response).
