Document Type and Number:
Japanese Patent JP2023158442
Kind Code:
A
Abstract:
To provide a power supply system that can prevent a situation where an imbalance between three phases occurs and can suppress the instability of an electric power system, and to provide a three-single phase inverter used for the system.SOLUTION: The present invention relates to a charging system that can perform fast charging to an electric vehicle and/or a battery system while supplying an electric power to each user's house from a commercial system. The charging system comprises: a three-phase wiring and/or a single-phase wiring for drawing the electric power into the user's house from a pole transformer arranged in the commercial system; ACDC converters corresponding to the number of distribution lines; and one or more DCAC inverters connected to the subsequent stage of the ACDC converter. In the charging system, the fast charging with DC is performed through parallel-connection of the electric vehicles and/or the battery systems by being branched from the distribution line connecting the ACDC converter to the DCAC converter.SELECTED DRAWING: Figure 3
