Abstract

PURPOSE:To conduct built-up in case of the built-up of the voltage of the generator positively by mounting a dead zone to an automatic voltage regulation which compares generator load voltage and reference voltage and extracts signals compensating errors. CONSTITUTION:When building up the output voltage of the AC generator 1, currents proportional to generator output voltage extracted through a reactor 3 and currents controlling currents proportional to generator output currents extracted through a current transformer 4 by means of a saturable current transformer 5 are composed and added to a semiconductor rectifier 6, and the field winding 8 of the AC exciter 7 is excited by the output of the rectifier 6. The automatic voltage regulator 13 addes deviation between the output of a generator output voltage detecting circuit 21 and the output of a reference voltage detecting circuit 24 to the base of a transistor 30, and addes the output of the transistor 30 to the DC exciting winding of the saturable current transformer 5.
