ABSTRACT:
A P-bar excitation system employs a generator having means for adjusting the voltage and current available from the P-bars. In some installations, the direct output of the P-bars can be connected directly to the rectifier and control circuit for development of dc excitation power. This permits elimination of the conventional excitation transformer and overall simplification of the excitation system. The voltage and current are adjusted using paired P-bars per phase, wherein each pair of P-bars is connected in series, and angularly displaced from each other about the inner circumference of the armature to attain a vector sum of voltages yielding and desired voltage per phase. In another embodiment, the generator magnetic flux, or equivalently, the number of armature turns is adjusted to yield the desired P-bar voltage and current.
