Inverter Design Based on the Low Voltage Treatment Device for Rural Power Grids

With the development of the economy, a large number of electronic products are connected to the rural power grid, causing the voltage at the user end to no longer be stable. The voltage fluctuation problem can be solved by flexible DC technology, so the inverter design of the low-voltage treatment device becomes the key point of the low-voltage treatment device. This paper considers an inverter device based on the low-voltage treatment device of the rural power grid. Firstly, a single-phase voltage-type inverter circuit model is established; secondly, a suitable PI-P control strategy is selected and the rationality of the model and control strategy is analyzed through the Bode diagram; finally, simulation and experimental verification are carried out. The results show that the device can effectively improve the voltage waveform at the user end and enhance the voltage stability of the system.
