1results about How to "Increase mutual inductance" patented technology

The application provides an energy storage valve submodule and a high-voltage direct-hanging energy storage system. The energy storage valve submodule comprises a power conversion circuit, a first capacitor, a first energy storage unit and a second energy storage unit. The first capacitor, the first energy storage unit and the second energy storage unit are all connected in parallel with the power conversion circuit. A first connecting line is arranged between the first energy storage unit and the power conversion circuit. A second connecting line is arranged between the second energy storage unit and the power conversion circuit. The difference between the equivalent inductance of the first connecting line and the equivalent inductance of the second connecting line is less than a preset threshold value. The application can inhibit the first energy storage unit and the second energy storage unit from generating an over-limit current at the switching moment when the energy storage valve submodule is put into operation and cut off, thereby reducing damage to the first energy storage unit and the second energy storage unit and improving the stability and reliability of the energy storage valve submodule.
