摘　　要：介绍了Visual C++.NET环境下用SCPI语言实现对大功率直流电源SM35-45的控制。通过获取列阵器件的V-II、dV/dI-I、P-I、dP/dI-I特性曲线,对其质量和可靠性进行了测试。测试结果表明:该电源的纹波系数、稳定度等参数能满足激光器列阵的驱动要求,所获取的评价激光器可靠性的结特征参量m、反映结的完整性及载流子泄漏的参量b等参数准确可靠,而且该测试系统有较好的稳定性。The control of the high-power direct current supply SM35-45 which has been used successfully in the nondestructive testing of the high-power semiconductor laser device array（LDA） was realized using the language SCPI in the integrated development environment Visual C＋＋. NET. Supplying stepped constant current to LDAs,their quality and reliability were tested and evaluated by their characteristics of V, IdV/DI, P, and dP/dI versus I, etc. The test results indicate that the parameters such as stability degree and ripple coefficient of this power supply satisfied the need of LDA driving, and the extracted parameters to evaluate the quality and reliabity of the LDA, m;b are exact and steady. It can be concluded that the developed testing system demonstrates excellent performance and stability.
