摘　　要：介绍一种新型的基于软开关投切技术的连续无功补偿装置,并设计出适用于该方案的基于ARM嵌入式微处理器的无功补偿控制器。采用基于32位ARM7TDMI嵌入式微处理器S3C44B0X和μC/OS-Ⅱ实时操作系统内核的交流同步采样方法。该方法较好地解决了精确性和实时性的矛盾。采用ADS7864用A/D芯片,简化了硬件接口电路。In this paper, a new kind of continuous reactive power compensator, which was based on soft switching, was introduced and a ARM-based controller was designed. A technology of AC synchronization sampling was given which was based on embedded microprocessor S3C44BOX with 32-bit ARM7TDMI core and μC/OS-Ⅱ real-time operating system kernel. The technology has decreased the conflict between the precision and real-time property. The A/D chip ADS7864 has predigested the interface circuit.
