Abstract


Papers for the special requirements of the digital generator , a way to meet a wide pressure and broadband input rectifier power supply design . Focus on analysis of the rectifier power supply design difficulties , the P89LPC935 microcontroller as the core , to design a digital input triggers applicable in the digital generators wide voltage , broadband rate ; unique throttle control digital generator rectifier power using a kinds a simple microcontroller lifting speed control of stepper motor . Experimental results show that the control power to not only be able to adapt wide pressure and Broadband input and substantial change in input voltage and frequency , and still be able to be a stable and reliable work , simple circuit , anti-interference ability and high cost performance . The paper mainly include the following aspects : ( 1 ) analysis of the research status of the digital generator and rectifier trigger characteristics of the domestic and international digital generator . About digital generator works . ( 2 ) elaborate digital power generator control system structure , has done a detailed analysis of the entire control of the power of the digital generator . Bridge rectifier , rectifier scheme to determine the device , as well as the pre -stage rectifier power control circuit program . On this basis , determine the design of the main circuit and control circuit . The ③ focus control circuit hardware design , including: 1) able to adapt to a wide frequency , wide voltage input digital trigger design , which is divided into synchronous circuit design , phase shift control circuit design , half-controlled bridge driver circuit design and detection circuit design ; 2 ) throttle control hardware circuit design . ④ analysis the entire preceding stage rectification power control features, combined with the control power hardware circuit to complete the rectification power software design . Mainly include : 1) stepper motor driver design ; 2 ) bridge rectifier control program design . Design difficulties , the acceleration and deceleration of the stepper motor control and rectifier bridge control frequency transformer control to do a detailed analysis . ⑤ of the development of the digital generator control power rectifier power experimental apparatus , the experimental study of the system , and verify that the system meets the design requirements .
