摘　　要：本文介绍了一种新型的稳弧电源实现方案,不但对理论基础、主电路拓扑、DSP(Digital Signal Processing)和CPLD(Complex Programmable Logic Device)等高性能芯片组成的控制系统进行了较为详细的介绍分析,还给出了部分具体的控制软件程序和电路实现方式。最终根据设计思路研制出试验样机,其输出波形的测试结果较为理想,验证了设计方案的合理性和可行性。A new design scheme of arc stabilization power supply is introduced in this paper. It not only gives a detailed analysis of the theoretical basis, the unique main circuit topology construction, the control system composed of high-performance chips such as DSP and CPLD, but also some specific control software programs and circuit implementation methods are presented.Finally, a test prototype is developed according to the design idea, and relatively ideal result is obtained by testing the output waveform, which verifies the rationality and feasibility of the design scheme.
