Generator voltage regulator on the basis of digital signal processor control

Abstract

The present invention discloses a generator voltage regulator on the basis of a digital signal processor control. The generator voltage regulator on the basis of the digital signal processor control comprises a digital signal processor, a memory, a timer, an analog-to-digital converter, a digital input interface, a second digital output interface, a power amplification circuit and a power tube. The memory, the timer, the analog-to-digital converter, the digital input interface, the digital output interface are connected with the digital signal processor, the power amplification circuit is connected with the digital output interface, and the power tube is connected with the power amplification circuit. The generator voltage regulator on the basis of digital signal processor control performs voltage regulation in the control of a digital signal processor and has small overshoot and short voltage buildup time when a generator builds voltage; when the generator is changed in work state, the transition process is short; and when the generator works normally, the stable state error is small.

Description

technical field [0001] The invention relates to a voltage regulator, in particular to a generator voltage regulator based on digital signal processor control. Background technique [0002] As a new type of generator, the electromagnetic brushless DC generator has a simple structure and no winding on the rotor, which is convenient for maintenance. However, after the three-phase voltage is full-wave rectified, a relatively large filter capacitor must be added to obtain a relatively stable voltage waveform. Due to the existence of the capacitor, the time constant of the entire power generation system increases, and the requirements for the voltage regulator are higher. Traditional voltage regulators have poor transient performance and steady-state performance and cannot meet the requirements. Contents of the invention [0003] The purpose of the present invention is to solve the problems mentioned above in the background technology section through a generator voltage regulat...
