System construction method of parallel operation system constructed with three electric power converters

Parallel operation systems have an advantage in that they can be constructed quickly and inexpensively by combining existing electric power converters. However, in this case, there is a peculiar problem in that a cross current flows between the electric power converters. To design a control system more simply and commonalize the core of combination reactors, we reviewed a system construction method for parallel operation systems constructed with three electric power converters.
