ABSTRACT:
A voltage regulator for a separately excited generator including a main generator unit having generating winding means and exciting winding means and an exciter comprising a magnet field type generator with the output connected through a rectifier to said exciting winding means, said voltage regulator comprising thyristor means connected to said output of said exciter to short the AC output from said exciter from being supplied to said exciting winding means of said main generator unit characterized by further comprising a voltage divider including first electric resistance means non-linear in voltage to current characteristic, and second electric resistance means said voltage divider connected to the output of said generating winding means of said main generator, with the output voltage across said first electric resistance means of said voltage divider connected through a Zener diode to the gate of said thyristor means.
