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 5):
The power conversion device according to  claim 1 ,\n wherein when the DC link voltage of the power converter cell having the converter stopped is dropped to less than a predetermined voltage, the converter charges a DC link capacitor such that the DC link voltage is the predetermined voltage or more.
