Description

technical field [0001] The invention relates to the field of series power circuits of photovoltaic panels, supercapacitors and power modules, in particular to an electromagnetic induction voltage equalizing device. Background technique [0002] Solar power generation is an emerging renewable energy utilization method, which is energy-saving and environmentally friendly, and is one of the main trends in future electricity consumption. Solar battery modules (also called solar panels) are the core part of the solar power generation system and the most important part of the solar power generation system. The quality and cost of solar panels will directly determine the quality and cost of the entire system. [0003] When using grid-connected photovoltaic cells to generate power for electrical equipment or store electricity for batteries, the voltage of a single photovoltaic cell is too low to be directly connected to an inverter for grid-connected power supply. To use photovolt...

Problems solved by technology

The unbalanced voltage of each photovoltaic cell may lead to a decline in the overall output power performance of the photovoltaic cell group, resulting in accelerated aging of the photovoltaic cell panels in the photovoltaic cell group, seriously affecting the service life of the photovoltaic cell group, resulting in a waste of limited resources. It will also cause the working voltage of the power system to be unstable during operation
