Abstract: A dual inverter control method is capable of improving power efficiency of an inverter and a motor by controlling a dual inverter through 6-step control to apply a voltage to the motor in a motor driving system using the dual inverter. The dual inverter control method for controlling first and second inverters having output terminals commonly connected to a motor includes comparing all voltage commands for driving the motor with the magnitude of a DC voltage commonly applied to the first and second inverters; and generating a first voltage command with respect to an output of the first inverter and a second voltage command with respect to an output of the second inverter by selectively applying high gain over voltage modulation (HOVM) depending on a comparison result.

Abstract: An apparatus and method are provided for compensating for a position error of a resolver that compensates for positions in the overall speed range using resolver position error measured at a specific speed by providing an angle tracking observer (ATO) for calculating angle information. The ATO compensates for the position errors in the overall speed range based on the position errors measured at the specific speed, to an inside of a resolver-digital converter. The method includes digitalizing detected position information of the motor rotor and receiving the digitalized position information from a resolver-digital converter to measure the position error. An electrical angular velocity of the position error is determined and the position error at the electrical angular velocity 0 is calculated and stored. The position error at a current electrical angular velocity is converted into and compensated for using the calculated position error based on the current electrical angular velocity.
