    In this paper presents the multi-level inverter which operates at the desired frequency. The desired frequency is designed with the filter on Phase Lock Loop (PLL) controller. This scheme proposed is controlled in the close-loop system by PLL controller and the tracking resonance controller. The multi-level inverter was used to drive the AC motor which changes the speed of the motor instantaneously. The PWM signal of the controller was controlled by PLL controller and designs the band-pass filter by resonance controller. This control scheme is estimated phase and frequency in DQ-Transform of the PLL controller with the AC motor characteristic. The speed of the motor was detected the position in the stationary frame. The current of the motor is used for feedback and generating the central frequency for controls the speed of the motor. The PLL controllers were tracked and lock the frequency of the desired signal which is determined high-precision and accuracy of switching sequence in PLL controller for motor control.
