Abstract
An apparatus for controlling an inverter is disclosed, the apparatus detecting a DC link voltage of the inverter and a load amount using an output current outputted from a motor to the inverter, and deducting a load amount detected at the time of occurrence of instantaneous power failure from a command frequency at the time of the occurrence of instantaneous power failure, whereby a command voltage and a command frequency driving the motor can be outputted.
Claims5
An apparatus for controlling an inverter, the apparatus comprising:
- a first detection unit detecting a DC link voltage of the inverter;
- a second detection unit detecting a load amount from an output current outputted from the inverter to a motor;
- and
- a controller deducting the load amount detected at the time of occurrence of instantaneous power failure from a command frequency at the time of the occurrence of instantaneous power failure to output a command voltage and a command frequency driving the motor.
