摘要
介绍了一种运用PWM-Buck电路和零电压开关技术的全桥逆变式高频高压电子束焊机电源及其控制系统,实现了高压电源输出电压的连续可调和过流过压的稳定保护及高稳压精度的要求,提高了系统的能量转换效率。
The inverter electron-beam welding power supply and its control system based on zero-voltage switching technology and PWM Buck circuit are presented. The control system is a kind of full bridge inverter with high energy-conversion efficiency,which can realize the continuous regulation to the output voltage of the high voltage power supply and meet the requirements of the well protection for over-current and high accuracy for steady voltage.
