摘　　要：介绍了一种为电流互感器暂态特性测试提供测试信号的电源的软硬件设计。该电源的功率电路采用单相交直交变频方式;控制电路以TMS320F2812 DSP控制系统为核心;控制策略选择输出电压基波有效值反馈控制方式。实验结果表明,该电源能够满足工业现场对电流互感器暂态特性测试电源的技术要求。The hardware and software design of transient characteristic test power supply for current transformer is introduced. This design is characterized with the method of single-phase frequency conversion employed in power circuit, TMS320F2812 DSP control system applied in control circuit, and control strategy selection of fundamental frequency RMS output voltage feedback control mode. The experimental results show that the power supply can meet the technical requirements in transient characteristic test of current transformer.
