Development of Inverter for Speed Control of 3 Phase Induction Motor

[@victoryfirst2878]

Nice job fella. Now I know who to talk to about speed control of three phase motors. Thanks

[@dhruvitsukhadwala8935]

Superb project....! Very thoroughly done!!!

[@umerarshad5022]

Great

[@amiliahasan3752]

I never thought of the dead band. thank you for the info. I'm going to design the 3phase inverter which also can be used to control the single phase motor for the trainer purposed. But I have a problem in doing the programming. I need to learn the arduino which looks more easy

[@RAJANVAMJA]

the speed of calculation is more important for making V/F control precisely. so please go for high speed controller in Arduino environment itself.

[@akashshah9893]

Great prototype.. cheers!!

Ok so the gate driver slowly turn on or is the optocoupler slowly turn on that’s what I wise to know

Good Job sir.. I want to know that if we used cd4047be ic for multivibrator task..do we need a dead band circuit for that?

[@bhardwajrajyaguru2601]

Not required.

[@KJ7JHN]

Nice job. You may need a p-channel mosfet after the igbt to prevent reverse current damage. As the washer powers through the agitation, it'll encounter a ton of reverse flux.

[@bhardwajrajyaguru2601]

We will try to update

[@Dc_tech386]

So it’s best to use p channel instead of igbt for this application or I would need to parallel p channel mosfet with the igbt

Which IC you used for dead band circuit

[@aldwayneparchment8140]

Do you have the arduino program for this

[@VamjaRajan]

NO.. it is difficult to generate SPWM pulse using Arduino.

[@aldwayneparchment8140]

Rajan patel so do you get to control the speed

[@VamjaRajan]

@@aldwayneparchment8140 yes, we do control the speed by modulating the inverter output voltage and its frequency in fix ratio. Here, SPWM control is implemented using ADVANCE timers of STM32f407VG controller.

Hello there, very good job the speaker explain everything very good, however, the dead time cct has been not mention in the presented cct. Do you left it from design ? thanks you in advance

[@RAJANVAMJA]

actually, we have used software dead band. we are using the STM32f407VG controller. which is providing facility to generated Inverter pulse with the required amount of dead band timing.it was 1.2 usec . and we have designed same dead band circuit and it was working fine..

[@rayvillalonga9077]

Hi guys i need your help i have a problem with this same kind of circuit

[@RAJANVAMJA]

how can we help you ?

[@krishnamurariprasad8165]

is there any way to manipulate the magnitudes of voltage and frequencies at same time manually to achieve desired torques and rpm? actually i want two controlling nobes in this vfd set up, through which i can control frequency and voltage manually at same time.

[@RAJANVAMJA]

yes.. it is quite possible. you can use ADC channel to give input of modulation index (which is proportional with voltage and frequency ). you can use VARIAC NOBE to change it. that is also available in our circuit. you can see in video at 7:46 time . parrallel to switch one nobe is connected. we can use it when we want analog control of drive.

[@mikekaranja6723]

Hello bro. Congratulations for your good job. I wanted to ask you some question . What the number of the IGBT are you using?? And also let me ask you the second question. That IGBT booster you build can it be controlled by Dc 400?? Hopefully to hear from you, thank you

[@RAJANVAMJA]

yes, it can be used with 400V dc but I suggest you to go up to 350V dc link with the IR2110 driver IC. if you want to go still higher than need a different type of driver circuit. whatever we have tried that was manually soldered. so giving higher voltage can lead to burning of the device or driver.

What component you're using for make deadband circuit, please answer me ? Thanks sir nice project

[@RAJANVAMJA]

you can design deadband circuit using NAND gate, registor and capacitor.. AS Shown in OUR VIDEO AT 5:43 time. or recently advanced controller have PWM TIMER-> This type of timer are PROVIDING advance compare operation and can generate COMPLIMENTED PWM PULSE with predefined DEAD BAND TIME. WE have utilized the PWM TIMER FROM controller STM32F407vg.

[@efrykaliky7363]

@@RAJANVAMJA thanks sir, my circuit already done. but why you're using 1 uS for dead band time delay ? i have 1 mS dead time delay with my circuit (1 mS generate by RC time constant, R=10Kohm and C=0.1 uF then we have delay = 10.000 x (0.1x10^-6) = 0.001 = 1mS), what happent if i put this pulse for three phase inverter using 180 degree conduction mode.... ? it's work or not ?

[@efrykaliky7363]

if ill use 1 uS for deadtime delay, i can't see the difference of PWM signal (S1 and S4). i have 1 uS with R=10 ohm and C=0.1 uF, then we have delay for deadtime is = 10 x (0.1s10^-6) = 0.000001 = 1 uS.

[@RAJANVAMJA]

actully we using SPWM for GENERATING output voltage. where switching frequency is 5kHZ. so it is having very small switching time. so i requied 1 us dead band. if you are puting higher dead band. it will reduce your output voltage. no other complication . you have to compromise with output voltage reduction

[@RAJANVAMJA]

yes it will work. but your output votlage will reduce considerably. because if your output voltage having frq. 50 hz than ur SQUAREWAVE will have 20ms time period. so ur output votlage will reduces by (2/20 times.)....!!! :)

[@ommaurya5201]

Hi, Great work for speed control of drive , Could you tell me that you are using IGBT or different type of MOSFET like N channel and P channel? and I see in gate driver there is common ground given to all IGBT emmiter side so my question is that all IGBT emmiter is sorted due to this. Could you resolve my problem regarding this??

[@RAJANVAMJA]

good question. we have used IGBT. and IR2110 IGBT driver is used to drive 1 lag of inverter. such three IR2110 Driver IC required to operated 6 igbt (3 LAG of Inverter (each lag contain two igbt.)) please explore more about IR2110.

Great job 😍 , my friend I want to tell you that I was planning to do a variable frequency drive for 3 phase induction motor using linear drive especially v/f open loop method , and I'm using ATMEGA 328p to generate the spwm signals to feed the ir2110 which controls the IGBT transistor , and now I'm in the process of building the program , so I was thinking of writing a look-up table for each frequency and voltage and ensure that v/f ratio always constant , can you tell me your thoughts about my project ( should I use a microcontroller like you have used or it's fine write my own code to generate pwm for 3 phase inverter ) , and if you have any information could help me please provided it . I apologise for this lonnnng comment ☺ and thanks a lot for sharing your project with us .

[@RAJANVAMJA]

we are happy to help you, dear friend. already we are helping person name;;y @KUSHAL N ... Who has commented like you and dedicated to do V/F CONTROL. actully your method to make lookup table is ancient. now in the market to fast controller are avalable with high proccesing speed. which can calculate sine in infraction of the microsecond. so i suggest you to go for STM32F407VG. now a days , STM32 is possible to program using directly from matlab simulink simillar like DSPACE2210(you may have heard name- it is consting 5lac rs aprox) . stm is cheap and quite affordable. till date we have done . 1)all chopper control 2) spwm , svm , (Thi open loop) 3) scallar closed loop control. 4) advance control : DTC AND FOC FOR INDUCTION MOTOR .. as well as PMSM AND BLDC. so better to shift to STM32F407vg.
