ExcIEEEAC7B Class
IEEE 421.5-2005 type AC7B model. The model represents excitation systems which consist of an AC alternator with either stationary or rotating rectifiers to produce the DC field requirements. It is an upgrade to earlier AC excitation systems, which replace only the controls but retain the AC alternator and diode rectifier bridge. Reference: IEEE 421.5-2005, 6.7. Note, however, that in IEEE 421.5-2005, the [1 / <i>sT</i><i><sub>E</sub></i>] block is shown as [1 / (1 + <i>sT</i><i><sub>E</sub></i>)], which is incorrect.
