Abstract

The control system for a converter and synchronous machine arrangement ensures a direct control of the operating component of the current and hence of the torque of the machine by the control angle with reduced current flow variation. The machine is connected to the three phase supply by a rectifier and its stator windings fed by a converter. This has thyristors and antiparallel-connected return diodes or reverse conducting thyristors. Between them is an inductance and a smoothing capacitor. A pulse transmitter determines the angle of the rotating field of the machine. The rectifier is controlled by a mains dependent device connected to a current controller operated by the difference between the nominal value from a voltage controller and the actual of the current in an intermediate circuit. The latter is dependent on a main supply indicator.
