DEVICE AND CONTROL METHOD OF CIRCULATING CURRENT IN THE INVERTERS SYSTEM Russian patent published in 2017 - IPC H02M7/48 

FIELD: electricity.

SUBSTANCE: power conversion system provides a multi-phase power supply, having phase voltages for each phase of the multiphase power supply. The system contains a variety of inverters, which generate the output voltage PWM, based on the control signals PWM. The variety of inductive components is made with possibility to receive the output voltages PWM to generate a phase voltages. Output voltages PWM cause the circulating currents flows through the variety of inductive components. The control device is applied to control the voltage, which is made with ability to respond to the phase voltage to generate the voltage modulating signal, corresponding to phase voltages. The variety of current redistribution channels are respectively associated with each of the variety of inductive components, and configured to generate the current redistribution modulating signal in response to the circulating currents flows. The control PWM-signals generating is provided, based on the modulating signals, obtained by combining the modulating signals of current redistribution and modulating voltage signals.

EFFECT: reliability increase.
