Abstract:
In a power conversion device in a configuration in which a plurality of power converter cells has serially connected outputs and includes a converter and an inverter as components, when a load is light, the cells also operate with a light load, and efficiency is reduced. A power conversion device has a plurality of power converter cells. The outputs of the cells are connected in series. The device has a controller that controls the cells. The cells each have a converter that converts an externally inputted power supply voltage and generates a DC link voltage and an inverter that converts the DC link voltage into an alternating current voltage and outputs the current. The controller stops a converter in some of the cells depending on power supply electric power or load electric power. The inverter continues to operate using a link capacitor as a power supply.

Claim (Index 1):
A power conversion device comprising:\n a plurality of power converter cells; and a controller configured to control the plurality of power converter cells, wherein the plurality of power converter cells has outputs connected in series, power converter cells in the plurality of power converter cells each have a converter configured to convert a voltage outputted from a power supply connected to inputs of the power converter cells and generate a DC link voltage, and an inverter configured to convert the DC link voltage into an alternating current voltage and output the alternating current voltage to a load connected to the outputs of the power converter cells, and the controller stops a converter in a given power converter cell in the power converter cells depending on power supply electric power outputted from the power supply or load electric power of the load.
