Pulse load excitation constant-voltage direct current generator regulator

Abstract

The invention provides a pulse load excitation constant-voltage direct current generator regulator. The input of the regulator is the voltage of the positive power supply and the negative power supply of a pulse load excitation constant-voltage direct current generator. The regulator comprises a positive power supply regulating circuit and a negative power supply regulating circuit; the output voltage of the regulator is input to the shunt-excitation magnetic winding of the generator; when the voltage of the positive power supply is not greater than positive and negative feedback conversion voltage, the positive power supply and the shunt-excitation magnetic winding of the generator are directly connected to form positive feedback to rapidly start the generator; and when the voltage of the positive power supply is greater than the positive and negative feedback conversion voltage, the positive power supply and the negative power supply are respectively connected with the positive power supply regulating circuit and the negative power supply regulating circuit to form a negative feedback circuit to output the voltage to control the generator. In the invention, a dual-feedback mode is adopted to regulate the excitation current of the shunt-excitation magnetic winding of the generator to control the positive output voltage and the negative output voltage of the generator under the pulse load condition. The regulator has the characteristics of simple structure, small volume, high voltage regulating speed and the like.
