A self-excited dc generator can be controlled by generator speed or by a rheostat or electronic circuit that reduces the field current. A combination could also be used.

WebThe advantage from the PMG is that the power to the AVR is kept near constant, allowing the AVR to quickly recover the voltage of the AC generator back to its nominal preset value. The AVR reacts quicker reducing the transient voltage dip associated with applying a load to an AC alternator. The PMG system also provides the advantage that no ... WebRe-arranging, the relationship between torque and speed for both separately excited and shunt excited machines is obtained: \[ \omega=\frac{V_T}{k\phi} …

WebFor shunt or series excited generators, the field winding is disconnected from the machine and connected across an external supply. Now, from the emf equation of dc generator, we know that Eg = kɸ. Hence, the generated emf should be directly proportional to field flux (and hence, also directly proportional to the field current).
