摘要

摘要: 针对150kV/30kW电子束焊接高压电源高电压、大功率输出的要求,低压电路采用IGBT (Insulated Gate Bipolar Transistor)逆变隔离直流电源与逆变全桥串联的主电路拓扑,高压电路由3组升压变压器与10倍压整流电路的串联结构并联组成;设计了高压采样电路、束流采样电路,以及双闭环控制电路.基于上述技术,实现了150kV/30kW高电压大功率输出.实验结果表明高压加速电源的输出线性度和束流输出线性度较好,同时高压稳定度和束流稳定度均在0.5%左右,能够满足电子束焊接的要求.

Abstract: With the consideration of characteristics of high voltage and high power output of 150kV/30kW power supply of electron beam welding (EBW), low-voltage circuit was designed to be composed of insulated gate bipolar transistor (IGBT) isolated DC power supply and full bridge inverter in series, and high-voltage circuit was paralleled by three groups of high-voltage transformer with 10 times voltage doubling rectifier circuit in series. At the same time, high voltage sampling circuit, electron beam current sampling circuit, and dual closed-loop control circuit were proposed. Based on the above technologies, the 150kV/30kW electron beam welding power supply was successfully developed. Experimental results show that the linearity of output voltage and output beam current of high-voltage accelerating power supply is excellent, the stability of output voltage and output beam current of high-voltage accelerating power supply is about 0.5%, which could satisfy the EBW requirements.
