    This research presented multilevel inverter using cascade transformers to supply the output voltage levels which are used to control speed of asymmetrical two-phase induction motor. Two sets of full bridge inverters and transformer with difference of number of turn ratio are combined to generate the voltage levels to supply each winding of asymmetrical two-phase induction motor. Triangular multicarrier sine pulse width modulation signal was generated by Arduino Due AT91SAM3X8E microcontroller and IC number IR2130 was used for power circuit. Multilevel inverter was presented to use a low level of input voltage as multilevel of output voltage is high that voltage stress on switches are reduced. The experiment shows the result of speed controlled by volt per hertz constant so as to be sure steady torque and PI method technique was used to closed-loop control.

    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.

    As Pure & Drinking water system is universally employed in Industrial,Reverse Osmosis System (ROS) has been becoming increasingly popular due to efficiency in Salt & Organic Rejection of it. However membrane system need regular cleaning. This paper present a new method for automation cleaning Reverse Osmosis System using Computer monitoring Process & analyze Trend of membrane performance & discuss enter to automation cleaning. The membrane performance consist of TDS, Water Flow, Pressure and Temperature. These variable analyzed for automation cleaning in order to maintain productivity and performance of RO System.

    In this paper, the computer aided teaching of power converter via Matlabl Simulink mainly concentrated on Power Factor Correction (PFC) topic to satisfy IEC 1000- 3-2. Quality improvement of input current to reduce current harmonics is demonstrated. Matlab/Simulink satisfied to nonlinear state space models, is used to increase system performances implementing and developing the controller included in toolbox i.e. sliding mode control, fuzzy logic control etc. The teaching module of power converter are classified to 3 topics 1) switching mode rectifier using single switch, 2) single phase ac-dc converter and 3) three phases ac-dc converter. However, with the Matlab/Simulink application, not only simulation time can be reduced but also convergence problem can he solved.
