FIELD: machine building.
SUBSTANCE: invention relates to devices for actuating three-phase motors. Technical result is achieved with the help of the film capacitors made with the ability to remove the ripple of the rectified voltage, in the DC link block, and a DC-to-AC conversion unit, which includes a three-level inverter receiving DC voltage from one pair of film capacitors to supply AC power to the motor.
EFFECT: technical result is to provide a motor driving device capable of providing a stable DC voltage and the neutral point voltage in a three-level inverter, even when a low-capacitor is used at the DC terminal.
