摘要： Disclosed herein is a method for controlling an inverter. The method includes calculating a maximum current from an output current of each phase of the inverter; determining a variable level upper limit by performing a DQ conversion for the output current of each phase of the inverter and adding a change allowable value to the DQ converted output current; determining a difference between the maximum current for each phase and the variable level upper limit as an output frequency attenuation variation, when the output current of the inverter arrives at the variable level upper limit; and determining an output frequency based on the output frequency attenuation variation.
