Abstract:
In order to achieve a power conversion device with which a motor can be stably driven, a power conversion device is provided with: an inverter, which converts supplied DC voltage to an AC output voltage and supplies the AC output voltage to windings, and which, in accordance with the DC voltage, changes the saturation level at which the output voltage is saturated, in order to drive a motor equipped with a stator having the windings and a rotor having permanent magnets; and a controller which, when the output voltage is lower than the saturation level, increases the output current of the inverter such that a magnetic flux that weakens or strengthens the magnetic flux generated by the permanent magnets is generated in the windings. An air conditioner including the power conversion device is also disclosed.

Claim (Index 5):
The power conversion device according to  claim 2 , wherein the controller comprises: a low-pass filter into which a value changes in response to a change in the DC voltage is input; and a weak field control unit configured to determine, based on an output signal from the low-pass filter, whether or not weak field control is executed.
