摘要
以逆变焊机为研究对象,为提高逆变焊接电源系统动态特性和控制精度,提出一种串联Boost预稳压输入,全桥逆变并联输出的逆变焊接电源主电路结构。分析了电路系统的功率传输原理和工作模态,进行了基于Matlab/Simulink的电路系统仿真设计,能更加直观地分析了电路的动态特性,并与传统的全桥逆变电路的仿真结果进行了对比。
This article focuses on inverter welder,in order to improve the dynamic characteristics and control accuracy of the inverter welding power system,the main circuit structure of the power supply system that the Boost voltage pre-regulator in series at input and the full bridge inverter in parallel at output is proposed. Analyzes the transmission principle and working modes of the power system,designs the circuit simulation system based on Matlab/Simulink presenting the dynamic characteristics intuitively,and compares the simulation results of the new system and traditional full bridge inverter system.
