摘要

电源转换器之间的通信对于高性能直流微电网控制至关重要。然而,对于住宅直流微电网应用,采用外部通信链路会增加系统成本,降低系统的灵活性和可靠性。本文提出了一种新的方法,使传统的DC/DC转换器通过公共直流总线传输数据。利用该技术,可以在直流微电网内建立电源转换器之间的低成本低带宽通信链路,并可以开发先进的分布式控制算法。通过共输入直流总线,实现了Boost转换器之间传输速率为2kbps的可靠通信。

Novel communication method between power converters for DC micro-grid applications
Communication between power converters is vital for high performance DC micro-grids controls. However, for residential DC micro-grid applications, using external communication link would increase the system cost, and reduce the system flexibility and reliability. This paper presents a novel method to enable the conventional DC/DC converters to transmit data via the common DC Bus. With this technology, cost-effective low bandwidth communication links between power converters can be established within a DC micro-grid, and advanced distributed control algorithms can be developed. A reliable communication with 2 kbps transmission rate has been implemented between the Boost converters through the common input DC bus.
