PROJECT DESCRIPTION

Sinusoidal PWM has been a very popular technique used in AC motor control. This relatively unsophisticated method employs a triangular carrier wave modulated by a sine wave and the points of intersection determine the switching points of the power devices in the inverter.

However, this method is unable to make full use of the inverter’s supply voltage and the asymmetrical nature of the PWM switching characteristics produces relatively high harmonic distortion in the supply.

Space Vector PWM (SVPWM) is a more sophisticated technique for generating a fundamental sine wave that provides a higher voltage to the motor and lower total harmonic distortion (THD). It is also compatible for use in vector control (Field orientation) of AC motors.

This abstract describes the theory of SVPWM and the project shall be made using a programmed microcontroller of 8051 family duly interfaced to 3 phase six pulse inverter with 6 no’s MOSFET from DC derived from a single phase mains or 3 phase, 50 Hz supply. The load shall be a three phase 50 Hz 440volt 0.5 HP motor. Alternatively a star lamp load can be used in place of motor to view the waveform only.

Further this project can be enhanced by using IGBT instead of MOSFET for higher voltage power operations. Speed control of the motor can also be achieved by V/F method.

NOTE: A 3 phase induction motor of 0.5HP or 1HP is required to see the output. Motor is not supplied along with the kit. However, it can be purchased at extra cost.

Q & A
Q:  Which microcontroller is used in this project?
A:  A 40 pin microcontroller from 8051 family is used in this project.
Q:  What is SVPWM?
A:  SPWM or sine pulse width modulation is a type of pulse modulation wherein the triangular carrier signal is compared with the sinusoidal reference signal to generate the pulse modulated signals.
Q:  What is the rating of motor to be used in this project?
A:  3 phase, ¼HP motor is used in this project.
Q:  Can one run single phase induction motor without capacitor?
A:  Model 240 is also available in single phase for Induction motor that requires no capacitor either in run or in start. The model develops 2 phases i.e. one out of phase by 90 degrees to the other which are then fed to 2 coils of the single phase Induction motor.

Faculty EEE hod referred from Baroda parul university
He suggested thats y we purchased
Yes i’ll refer my juniors and freinds

I was searching final year project in google then i got to know about edgefx then i have directly visited the website..
I have decided to buy project from edgefx because there is no other website like this i have ever seen. And, it is providing the readymade kit that is why i have purchased project from edgefx. I like whole Readymade Kit.
the kit was delivered in time with right components.
the support team has helped me in purchasing the project.
i want to give reference to my juniors.

I got to know about edgefx through google. And, the keywords i used to find edgefx was single phase to three phase converter project in google
I have decided to buy project from edgefx was the project i have decided was complicated one. And, i don’t know to do in real time. So, i have decided to buy project from edgefx. And, i like most about edgefx was Raspberry Pi.
kit was delivered on time.
i have got a number in website.. So, i called that number and they helped me.
i already gave references to my friend, he has also purchased project from edgefx.

I had find this website by searching the keyword space related projects.
Myself decided to buy because of very good documentation,ppt provided as sample and my requirement is available in this project.
Got it through online.
