Five-phase half-controlled bridge commutation and stabilizing voltage Nd-Fe-B permanent-magnet generator for light vehicle
Applied Mechanics and Materials(2012)
Abstract
Nd-Fe-B permanent-magnet generator provides DC power for the electrical equipment of light vehicle and charges the battery. The rotor of this generator is constructed by several fastening segments of Nd-Fe-B permanent-magnet material onto the iron core through pole shoes by nonmagnetic bolts with adjacent magnet segments opposed to each other in polarity, i.e. N poles and S poles arrayed alternately. When the rotor rotation, hence the magnetic field rotates, the armature winding cuts the magnetic line and produces electromotive force. The developed five-phase half-controlled bridge commutation and stabilizing voltage adjuster combines both functions of voltage stabilization, commutation, and output direct current (DC) with stable voltage. The instability of output voltage was overcome when the permanent-magnet generator for light vehicle ran at wide range of speed and load. © (2012) Trans Tech Publications, Switzerland.
