[Contributions to the study of the electronic communication motor. I. Theoretical and experimental study of the controlled rectifier generator]

This paper presents an application of the commutation circuit theory to the study of the controlled rectifier generator: that is the association of a synchronous machine with a controlled rectifier where the triggering of thyristors is controlled by a sensor of the relative position field/armature. The three-phase generator associated with a full-wave bridge rectifier is especially studied. The analysis shows several possible operation modes: the controlled rectifier operation mode, the uncontrolled rectifier operation mode and the commutation failure causing an alternator operation mode. The developed model, suitable for transient analysis, could be used for the study of controlled rectifying and the behaviour of the electronic commutation DC motor (synchronous type).Francai
