中文摘要:
      提出了一种对误差信息进行多精度反馈编码的方法。该方法通过将主模块的电流基准值的误差信息进行多精度反馈编码,然后传输到从模块,主从模块都通过误差信息来恢复电流的基准值,实现并联变换器均流。与传统的将主模块的电流基准值信息直接进行编码发送到从模块相比,该方法在电流基准信息发生改变时仍然有效。通过对编码区间段进行合理地划分,可以在不增加传输数据量的同时,提高有效数据位的利用率。通过对误差信息多精度反馈编码,可以有效降低无线网络延时对系统的影响,从而进一步提高无线并联系统的开关频率。最后,实验验证了该方法的有效性。
英文摘要:
      A multi-precision feedback coding method based on error information is proposed. In this method, the error information of the current reference value in the master module is subjected to multi-precision feedback coding, and then transmitted to the slave modules. Both the master and slave modules recover the current reference value by using the error information to realize the parallel current sharing in the parallel converter. Compared with the conventional method of transmitting the current reference information from the master module directly to the slave modules, the proposed one is still effective especially when the current reference information is changed. By appropriately dividing the coding interval into several parts, it is possible to improve the utilization ratio of the effective data bits without increasing the amount of transmission data. The multi-precision feedback coding for error information can effectively reduce effects, bringing by the wireless network delay, on the parallel system’s performance. It is rather important for the improvement of the switching frequency of the whole system. Finally, the effectiveness of the method is verified by the experimental results.
