Claim Text:
1. A dual inverter system to drive a motor in an electronic apparatus, the dual inverter system comprising: a first inverter connected to one side of a winding of the motor to modulate a pulse width and to adjust power supplied to the motor; a second inverter connected to the other side of the winding of the motor to modulate a pulse width and to adjust power supplied to the motor; a first current detector connected to the first inverter to detect a current flowing in the first inverter; a second current detector connected to the second inverter to detect a current flowing in the second inverter; and a controller to control the motor by controlling a pulse-width modulation (PWM) signal applied to the first inverter or the second inverter based on the current flowing in at least one of the first inverter and the second inverter.
