Common low-voltage inverters in China include single-phase 220V inverters, three-phase 220V inverters, and i-phase 380V inverters. High-voltage inverters are commonly found in 6kV and 10kV transformers. The control method is generally changed in a high-low-high inverter or a high-high inverter. In the assembly and production process of the inverter, more parts and more processes are involved. At present, when assembling the inverter, it is necessary to use an assembly positioning device to fix it.
