Inverter and inverter device
First Claim
1. An inverter comprising:
- a detector which detects a value corresponding to an output voltage and a value of an output current;
a command value input unit which is capable of receiving a current command value;
a current command value compensating unit which, when the value of the output voltage detected by the detector is equal to or lower than a predetermined value, computes a compensation current value for compensating the current command value;
an adder which adds the compensation current value to the current command value and outputs the compensated current command value; and
a current controller which computes a voltage command value so that a difference between the compensated current command value and the output current detected by the detector becomes zero.

Abstract
According to one embodiment, an inverter including a detector which detects a value of an output voltage and a value of an output current; a command value input unit which is capable of receiving a current command value; a current command value compensating unit which, when the value of the output voltage detected by the detector is equal to or lower than a predetermined value, computes a compensation current value for compensating the current command value; an adder which adds the compensation current value to the current command value and outputs the compensated current command value; and a current controller which computes a voltage command value so that a difference between the compensated current command value and the output current detected by the detector becomes zero.
