摘　　要：为了满足对大功率集成电路器件的测试需求,需要在测试系统中使用大功率负载驱动能力的电压电流源;该系统采用了四象限钳位、输出继电器保护和创新性的调压恒流技术,改善了传统大功率电压电流源设计的局限性;系统输出电压电流范围宽并且输出值精确;应用结果表明,该检测系统运行稳定可靠,测量精度高。An advanced power Ⅵ source is developed to used in IC automatic test equipment area. The precision and efficiency of the Ⅵ source output has been improved due to the special design techniques. A creative voltage adjustment design has been used to ensure the Ⅵ source has 2A constant current output ability. The application shows that this system runs stably and accurately. The technology and methods adopted in the system are practical and worthy of using abroad.
