Hi there……
I very much like your work on VFD 3 Phase Induction Motor Sine-PWM using Arduino UNO. But i am unable to see components that you use in your rectifier PCB board. Can you please send me components list and detailed connection diagram?
Hi, Hussnain
For the power supply is in the finished box. (In the video clip 0.50) DC Power supply for Motor, which internally uses a full-wave rectifier diode bridge and uses a filter capacitor to provide direct current.

Hi,
Sir, i have been very fascinated by your one of the video, arduino control of half bridge inverter for induction heating.
Would you please help me to make an induction cooker circuit by using full bridge inverter. I am uing 48 V dc source.I have tried several times to implement hardware implementation but failed. It would be great if you please make a video on that or, give me the necessary component required to make this circuit, i would design. I need this badly.
Hi, Mahfuz
If I have a chance, I will study and test the full bridge inverter circuit and share. You can learn about induction cooker circuit by using full bridge inverter following link.

Hello!
Modul SRM400 Pro-Wave
Sonar Modul SRM 400 Pro-Wave Is there documentation for the dimensioning of the bandpass for your sonar IC PW0268 or a table for different frequencies or a calculation method for the bandpass especially in this IC? I need a dimensioning for 200 Khz. I haven’t found anything anywhere. Is there a description of the Ic for developers?
I look forward to your reply.
Best regards
Herbert Dücker
Hi, Herbert
.
For the experiment I have presented as a preliminary experiment and using the document (PDF) at the link shown on the website.
And applied to the example program HC-SR04 to be able to use with the Ultrasonic Transducer sensor as a guideline.
In the experiment, the recommended details can be found in the reference link at the end of the project.

อยากให้ออกแบบ ไมโครอินเวอรเตอร์หน่อยครับ ขนาดประมาณสัก 250w
สวัสดีครับ คุณอนุวัฒนา
สำหรับการออกแบบไมโครอินเวอรเตอร์ ผมเคยศึกษาหลักการทำงานไว้บ้าง แต่ยังไม่ได้นำเสนอเนื้อหาและการทดลอง อย่างไรแล้วจะนำมาเสนอให้นะครับ
ช่วงนี้ผมกำลังศึกษาดีซี ทู ดีซี คอนเวอร์เตอร์แบบใช้เทคนิคให้ประสิทธิภาพสูง (High efficiency dc-dc converter) และการปรับค่าตัวประกอบกำลังไฟฟ้า (ActivePFC) ครับ.

Hi bro,
I make the hardware as per your circuit
“Arduino Speed Control 3 Phase Induction Motor by TM-35 (V.2)”
code is working fine and also the hardware
later I for the same hardware I put this SPWM code with the ports changed as per the code
the IPM module is getting short .again I replaced the IPM module and put the old TM-35 code and tested .its working. Again I put the SPWM code the IPM got shorted.
Took the code form this link
https://www.electronicsdna.com/simple-test-svpwm-3-phase-induction-motor-by-arduino-uno/
please can you tell me the reason?
Is TM-35 3 phase sine wave code?
Thanks

Hi Nattapon,
Thank you so much for your reply.I have few questions.
I want to do a simple 3 phase induction motor driver. this has to work like the commercial VFD unit. but don’t need the function of the VFD.
Just when power on the motor should start form 100 rpm and reach the maximum.
I tried couple of codes available online .but in all the intial current is very high.
but in VFD the voltage current is syncronised with speed. current and voltages increases slowly.
Can u share me a code for this in arduino?
Can u share me your email id?
regards
venkatesh
Hi, venkatesh
“VFD the voltage current is syncronised with speed. current and voltages increases slowly.”
.
Introduce examples of programs according to the website link below.
https://www.electronicsdna.com/arduino-control-pure-sine-wave-inverter-lep/
.
Please consider the order. that can be used to adjust the speed and current gradually increase to the 3 phase motor
ValueFB = analogRead(A1); // Voltage FB
if(ValueFB>500 && k>0.1) k-=0.01;
if(ValueFB<500 && k<0.99) k+=0.01;
-----------------------------------------------------------
OCR1A = pgm_read_byte_near(sine256 + phase1)*k; // pwm pin 9 (+B)
OCR1B = OCR1A+3; // pwm pin 10
OCR0A = pgm_read_byte_near(sine256 + phase2)*k; // pwm pin 6 (+B)
OCR0B = OCR0A+3; // pwm pin 5
*** You can experiment with adjusting the Arduino Code to make the motor control work as you want.

hello sir,
I hope you are alright.i want to discuss something with you according to my project i am making single to three phase converter by using svpwm. my project have first take single phase input then rectify, filter, then IGBTmodule (inverter) then I have 3 Phase Induction Motor as a load , IGBTmodule (inverter) which is driven by arduino uno I am using your mentioned code of SVPWM 3 Phase Induction Motor with Arduino UNO I have not implemented on hardware yet as i was looking at the output of SVPWM on hardware I am feeling there is a dead time in the output wave of complimentary switches so I am afraid to implemented. can you tell me i am wrong or what? should I drive without any hesitation?if you are easy then can you give me your email so I can share some output and talk more about this project.I hope you will help me. Thank you in advance
Hi, Talha Ahmed
“I am afraid to implemented”
.
I was also scared for the 3 phase motor test drive as well. Recommended to use a constant resistor of about 100 ohm/30 watts or incandescent bulbs (100 watts) in series with
the high voltage power supply for the IGBT module in the experiment. Preliminary The motor will be able to rotate normally and will not cause abnormal heat to the IGBT module. After
that, power can be directly supplied to the IGBT module for testing the 3 phase motor for objective.

Hi, venkatesh
“I am not so good in coding.”
I recommend reading more books about Arduino Code Basics. This example Arduino Code is shown in this website link. [https://www.electronicsdna.com/arduino-control-pure-sine-wave-inverter-lep/] and then doing step-by-step experiments.
.

Hi Nattapon,
Can you please make the code for me. will pay your charges.
what is need is
1) 6 pins with UH,UL,VH,VL,WH,WL . ANY ARDUINO MICROCNTROLLER
2) syncronised with speed. current and voltages increases slowly.EXAMPLE FROM 100 RPM TO MAXIMUM.
no need to implement on hardware. only verify by scope and give me. rest I will do.

Hi Sir,
Will Try To make Test Projects For VFD, As Per Ur Reference Video & Arduino.
Wnat to know some Queris
1] Can we connect DC 220V to Motor Supply ? (220V AC Rectify With Bridge Rectifire + Fillter Capacitor)
in the video we see ur connect motor with DC 160V.
2] Can we used MOSFET withe Driver ICS’ ? Insted of IPM Module
Hi, David
Answer the questions as follows:
(https://www.electronicsdna.com/vfd-3-phase-induction-motor-spwm/)
.
1. You can use 220V AC Rectify With Bridge Rectifier + Filter Capacitor (Approximately 310VDC) to experiment and use it.
2. You can use MOSFET with Driver ICS instead of IPM Module, but it may take more time to assemble and verify operation.

ให้ใช้dutyแค่ค่าเดียวคือ0.4อะครับ
ในกรณีที่แรงดันต่ำลงมากช่วงจ่ายกระแสโหลด และเราคำนวณค่าตัวเหนี่ยวนำ L-boost ได้ถูกต้องแล้ว ลองใช้ลวดทองแดงของ L-boost ให้มีขนาดใหญ่ขึ้นครับ.

Hi,
I am using the code for the Tiny Prototype for 3-phase Intelligent Power Module but it does not have ADC activated for speed control, apricate the code that includes the same, also how do I adjust the deadtime.
Hi, Mallickarjuna AS
For Arduino program code, I have developed from the reference program code (https://github.com/cmasenas/3-Phase-Sine-Arduino/blob/Release/DDS_Generator.ino) to be able to adjust the speed with VR from the ADC signal, including setting Timer0-2, OCRxx registers and constants to adjust the deadtime value.
In addition, we can use the IR2111 IC to separate the Hi Side and Lo Side signals from the circuit in the link.—> (https://www.electronicsdna.com/prototype-power-igbt-driver-board-for-3-phase-induction-motor/)
