Abstract :
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.
