| Abstract: | Nd-Fe-B permanent-magnet rotor is used in a 42V automotive generator.The theory of voltage stability for the permanent-magnet rotor generator is expounded with the relation of armature-reaction reactance,winding leakage reactance and load terminal voltage versus generator speed analyzed.A voltage stabilizer with five-phase semi-control bridge rectification is developed,which integrates the functions of voltage stabilization and current rectification and is composed of reference circuit,comparator circuit,tr... |
