传统电力线通信方案的硬件设计较为复杂。DC-DC变换器具有发送数据的潜能,可进行功率/数据复合传输。文中提出一种基于四进制频移键控(QFSK)调制的电力电子开关调制方案,通过调制开关频率将数据信息嵌入原始脉宽调制(PWM)信号中,使得电压纹波携带数据的频率特征;再通过基于滑动离散傅里叶变换的解调方案实现数据接收,最终实现功率/数据的同步传输。首先,证明了PWM信号与电压纹波频率一致的关系;然后,给出数据调制与解调的方案;以负载突变工况为例,通过对Buck变换器建模,分析功率变换暂态过程对通信的干扰影响;最后,搭建由两个Buck变换器组成的实验平台,验证了所提方案可实现20 kbit/s的通信速率;并以光伏优化器为应用背景,验证了所提方案的有效性。
The hardware design of traditional power line communication scheme is complex. The DC-DC converter has the potential to send data
and can carry out power/data multiplexing transmission. In this paper
a modulation scheme for power electronic switch based on quadrature frequency shift keying is proposed. By modulating the switch frequency
the data information is embedded into the original pulse width modulation (PWM) signal
so that the voltage ripple carries the frequency characteristics of the data. Then the data receiving is realized by the demodulation scheme based on sliding discrete Fourier transform
and ultimately the synchronous transmission of power/data is realized. Firstly
the relationship between PWM signal and voltage ripple frequency is proven; Then
the schemes of data modulation and demodulation are presented; Taking the load changing condition as an example
the buck converter is modeled to analyze the interference of power conversion transient process on communication; Finally
an experimental platform composed of two buck converters is built to achieve a communication rate of 20 kbit/s. The effectiveness of the proposed scheme is verified with the photovoltaic optimizer as the application background.
