The system comprises multiple three-phase inverter modules. The multiple three-phase inverter modules are in parallel connection with each other. Any two-phase circuit of a three-phase inverter module is separately in parallel connection with a corresponding two-phase circuit of a three-phase inverter module adjacent to the three-phase inverter module by using a connecting line module. The connecting line module is connected to a control system. The three-phase inverter modules are also connected to the control system. The three-phase lines of the three-phase inverter modules are all provided with switches. Less interconnecting lines are used, and any two phases of the three-phase inverter modules are separately in parallel connection, and therefore, stable power supply is achieved by balancing currents of any two phases of the three-phase circuits, and the system reliability is improved."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"System and method for parallel power supply control for auxiliary converters of motor train unit in presence of interconnecting lines","description":"A system and a method for parallel power supply control for auxiliary converters of a motor train unit in the presence of interconnecting lines.
