    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.

    This research is design and construct of Sine Pulse Width Modulation (SPWM) 4-leg voltage source inverter for controlling speed of asymmetrical two-phase induction motor. The Sine PWM switching signal is generated by ARM7 (Adu7024) microcontroller which is programmable and cheap, while having high frequency to generating switching signal. Two ICs No. IR2130 are used for motor driving part. The characteristics of output current signal are nearly closed to sinusoidal pattern resulting to high efficiency for motor control. In order to control the speed of induction motor, ratios of voltage to frequency (V/f) are controlled and constant torques are obtained by implementing technique of PI close-loop control.

    This research is design and construct of Sine Pulse Width Modulation (SPWM) 3-leg voltage source inverter for controlling speed of asymmetrical two-phase induction motor. ICs No. IRF2130 are used for motor driving part. The characteristics of output current signal are nearly closed to sinusoidal pattern, so that low harmonics and high efficiency for motor control are obtained. The Sine PWM switching signal is generated by ARM7 (Adu7024) micro-controller which is programmable and cheap, while having high frequency to generating switching signal. In order to control the speed of induction motor, ratios of voltage to frequency (V/f) are controlled and constant torques are obtained by implementing technique of PI close-loop control.
