SYSTEM AND METHOD OF PARALLEL POWER SUPPLY CONTROL FOR TRAIN MOTOR CAR UNIT AUXILIARY CONVERTERS IN PRESENCE OF CONNECTION LINES Russian patent published in 2017 - IPC H02M7/42 

FIELD: electrical engineering.

SUBSTANCE: using in electrical engineering. System of parallel power supply control for train motor car unit auxiliary converters in presence of connection lines comprises plurality of three-phase inverter modules, connected in parallel to each other. Any three-phase inverter module two-phase circuit separately connected in parallel to corresponding three-phase inverter module two-phase circuit, adjacent to said three-phase inverter module, using connecting line module. Connecting line module is connected to control system. Three-phase inverter modules are also connected to control system. All three-phase inverter modules three-phase lines are equipped with circuit breakers.

EFFECT: using less connection lines, and three-phase inverter modules any two phases are separately connected in parallel, thus achieving technical result, consisting in stable power supply by means of balancing of currents of any two phases of three-phase circuits and, consequently, increase in system reliability.
