摘　　要：介绍一种以高性能的16位数字信号控制器(DSC,digital signal controller)dsPIC30F4011为核心的数字化逆变电源控制系统,适用于软开关全桥逆变电路。采用数字化PWM/PFM无缝切换技术应用于逆变式多功能脉冲TIG焊机,实现3 A小电流接触引弧,使电源的输出功率具有更大的动态范围,解决了高频引弧对焊机造成的干扰及数字化多功能焊机稳定性难以保证等一系列问题,提高了电源的可靠性和易用性。This paper introduces the control system of digital inverter power source which is controlled by the high performance and 16 bit digital signal controller. The system achieves 3 A low current touch are starting which is applied to inverter type multifunctional pulse TIG welding machine. It makes the power output have more dynamic range.With the technology, the power source solved interference caused by the high frequency arc welder and stability of the digital muhiftmction is difficult to ensure and so on.So it improved the reliability and ease of use to the power source.
