Fundamental study of ultra small power electronics controller using dynamic reconfigurable processor

提出了一种基于动态可重构处理器（DRP）的电力电子数字控制系统。最近，DRP被开发并发布到消费者市场。DRP具有在一个时钟周期内改变多个计算电路配置的动态可重构特性。因此，在不牺牲计算性能的前提下，可以降低处理器的资源开销和功耗开销。证明了DRP有可能成为电力电子应用的一种有效解决方案。通过研究，将DRP应用于自主分散式单相UPS系统的控制器，阐述了系统的设计思想，讨论了系统资源消耗的考虑，证实了DRP适合于未来电力电子控制器。

A new digital control system using Dynamic Reconfigurable Processor(DRP) was proposed for power electronics controllers. Recently, DRP was developed and released to the consumer market. DRP has the dynamic reconfigurable features to change the plural calculation circuit configuration in one clock duration. So the resource cost and the power cost of the processor can be decreased without the trade off of the calculation performance. It was confirmed that DRP has the possibility to become one effective solution for the power electronics applications. Through this research, DRP is applied for the controller of the autonomous decentralized single phase UPS system, the design concept of the system were described and the consideration of the resource consumption were discussed, and it was confirmed that DRP is suitable for future power electronics controllers.
