For the first time, the recently proposed “talkative power” paradigm combining power electronics and communication engineering is extended by channel coding and advanced receiver design aspects. In this concept, the pulses that control the duty cycle of switched-mode power converters are simultaneously used for data transmission by modifying the pulse phase, pulse frequency, pulse position or pulse width. The data sequence is embedded into the switching signal, similar to random modulation. The data can be used for example in point-to-point links, inside multi-port power converters, and for communication in networked power grids. As an application example a buck converter is studied. Its output voltage is numerically calculated for arbitrary two-level switching signals. The corresponding system model serves as a common framework for switching waveform design, receiver design, and performance analysis. The data sequence is represented by a small deterministic output voltage ripple. Various techniques to improve the data rate and the robustness of the communication are introduced, including line coding, a derivation of the optimum receiver in the sense of maximum-likelihood detection, and forward error correction coding as an option. Although emphasis is on a buck converter, the concept is applicable to other power converter topologies as well.

用于同步有线信息和电力传输的信道编码和接收器设计


最近提出的将电力电子和通信工程相结合的“谈话功率”范例首次通过信道编码和先进的接收器设计方面进行了扩展。在此概念中，通过修改脉冲相位、脉冲频率、脉冲位置或脉冲宽度，控制开关模式功率转换器的占空比的脉冲同时用于数据传输。数据序列嵌入到开关信号中，类似于随机调制。这些数据可用于点对点链路、多端口电力转换器内部以及网络电网中的通信。作为一个应用示例，我们研究了降压转换器。其输出电压针对任意两电平开关信号进行数值计算。相应的系统模型充当开关波形设计、接收器设计和性能分析的通用框架。数据序列由小的确定性输出电压纹波表示。引入了提高数据速率和通信鲁棒性的各种技术，包括线路编码、最大似然检测意义上的最佳接收器的推导以及作为选项的前向纠错编码。尽管重点是降压转换器，但该概念也适用于其他电源转换器拓扑。
