Abstract:
A dual inverter system to drive a motor in an electronic apparatus and a method of controlling the same include a first inverter connected to one side of a stator 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 stator 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.
