Three phase rectifier and control system for heavy DC machine, combines armature and field current rectifiers in single unit and dispenses with separate chokes
Three phase rectifier and control system for heavy DC machine, combines armature and field current rectifiers in single unit and dispenses with separate chokes
Rectifier circuits for field (12) and armature (4) share common commutation chokes (2). The field current rectifier circuit includes controlled semiconductor switching (7), preferably using an IGBT transistor.
