Description

technical field [0001] The present invention mainly relates to the technical field of photovoltaic power generation. To be precise, a scheme in which power optimization circuits are used in photovoltaic modules is adopted, and the power optimization circuits can use power carrier signals to send data to ensure that the output of the entire photovoltaic module is Maximization of power and communication functions for sending data. Background technique [0002] With the industrialization process of some developing countries such as China, the frequency of extremely harsh environments such as smog has appeared, and countries around the world have generally recognized that: to seek an inexhaustible and recurring renewable energy to replace limited resources and harmful to the environment The polluting traditional chemical energy has become an important proposition that needs to be solved urgently. The development of science and technology based on new technology and new material...

Sampling like this to improve the reliability of the signal is only one aspect, but in the case where the photovoltaic cell and the carrier are applied at the same time, the voltage level of the photovoltaic cell itself will be greatly changed due to the influence of the ambient temperature and the intensity of light radiation. , so the distortion of the carrier signal on the power line itself and the battery’s output characteristics that are easy to fluctuate are mixed together, resulting in inaccurate real carrier signals that the receiver expects to capture and high bit error rates. The voltage superimposed on the strings is also subject to carrier interference, so the actual voltage on the entire string may not be within the expected range
