摘要： A three-level power conversion apparatus can suppress fluctuation in a neutral point voltage even when operated as a reactive power regulator. The three-level power conversion apparatus is composed of first and second three-level converters connected to an AC power supply, positive side and negative side DC capacitors, a three-level inverter to drive an AC motor, and converter control unit for controlling the three-level converters. The converter control unit has first and second reactive current controllers for controlling so that reactive portions of input currents of each three-level converter become a prescribed reactive current reference, first and second neutral point voltage fluctuation suppressing units for controlling a PWM controller, to make a voltage difference of two DC capacitors zero, and an active current controller for supplying a prescribed circulating active current from one three-level converter to other three-level converter.

摘要： To provide a three-level power conversion apparatus which can suppress fluctuation in a neutral point voltage even when operated as a reactive power regulator. The three-level power conversion apparatus is composed of first and second three-level converters 2A, 2B connected to an AC power supply system, positive side and negative side DC capacitors 3P, 3N, a three-level inverter 4 to drive an AC motor 5, and converter control means 10 for controlling the three-level converters 2A, 2B. The converter control means 10 has first and second reactive current control means 15A, 15B for controlling so that reactive portions of input currents of the three-level converters 2A, 2B become a prescribed reactive current reference, respectively, first and second neutral point voltage fluctuation suppressing means for controlling PWM control means 17A, 17B, respectively, so as to make a difference between voltages applied to DC capacitors 3P, 3N to be zero, and active current control means for supplying a prescribed circulating active current from the three-level converter 2A to the three-level converter 2B.

摘要： A power conversion apparatus is provided to prevent the arc flash generated in a board from flowing out to a operation surface for operating the board, and also to relieve the pressure inside the board to the outside from the flapper section provided on the ceiling. The power conversion apparatus that has taken measures against an arc flash composed of a power converter and a board accommodating the power converter is provided. A BUS which constitutes the power converter has the first processing that makes it hard to fly the flash in a place where arc flash is not desired to occur. A door is placed on the front board that can be opened and closed by the operator. The board has an explosion-proof shutter part to prevent the arc flash from being released to the outside by the pressure inside the board, and has a flapper section for releasing the pressure inside the board to the outside from the ceiling of the board unit, when the arc flash occurs.
