information from the state intellectual property office shows that sunshine power supply co., ltd. applied for a patent entitled “ voltage regulation method, power converter and inverter system “, with publication number CN121749751A and application date October 2025.
The patent abstract shows that this application provides a voltage regulation method, power converter and inverter system . The method includes: when each DC conversion circuit of the power converter is in In the case of bypass working mode, obtain the working condition parameters of each DC conversion circuit; the input end of each DC conversion circuit is used to connect a DC source, the power converter further includes an inverter circuit and a DC bus, the output end of each DC conversion circuit is connected to the DC side of the inverter circuit through the DC bus, and the AC output end of the inverter circuit is used to connect to the AC power supply network; when it is detected that at least one DC conversion circuit meets the output abnormality condition according to the operating condition parameter, the voltage of the DC bus is reduced, so that the DC conversion circuit meeting the output abnormality condition outputs power to the DC bus. That is, through the present application, the overall energy transmission capability of the power converter can be improved, and the energy loss can be reduced.
