基于DSP的电子束焊接高压逆变电源控制系统的研制
Study on the control system of high voltage interter power source in electron beam welding based on DSP
摘要
Abstract
A digital control system of power supply for EB welder is developed, which adopts DSP TMS320LF2407 as the core.The DSP general-purpose timer and its corresponding registers are used to produce programming PWM pulses,which frequency is up to 20 kHz. The turn on time and dead time of PWM pulses can be regulated. The protection circuits are designed to protect IGBT from overvoltagc, undervoltage and overcurrenl The optical fiber sampling circuits are used to sample the bias and high voltage-Constant voltage characteristic of the power souce is achieved by using the position PID control algorithm The system software flow chart is given in this paper. Experiments show that the power supply, which controlled by the digital control system, can reliably output the setting voltage at no load.关键词
