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.
