VFD Drive ? || Power Card, Control Card & IGBT Explained || AC VFD Working || VFD Repairing

In this video, we have explained the Internal Electronics of the VFD System. The purpose of this video is to understand the Power Card, Control Card & IGBT.
We have taken all the topics with the Circuit Diagram of VFD Drive.
The topics we covered are:
1) Rectifier Circuit.
2) Capacitor Bank
3) Recharge Resistor.
4) Breaking Resistor
5) IGBT
6) SMPS Circuit of VFD.
We have also designed similar videos for VFD Applications

Well explained sir and great opportunity to learn about internal circuit of VFD.

[@zunairaelectrical5565]

Kitne simple tarike se aap ne pura explane kar diya . Ab tak ki sabse achchi video hai ye jo mai dekha UA-cam pe.. so knowlegble sir keep it up . And thank u for helping us

[@visionworldtech]

Thank you for your response, we will try to upload more videos like this. 😊

[@zunairaelectrical5565]

Sir one more question.. IGBT KO kaunsi circuit operate karti hai uska circuit digram share kariye

[@rohitroy7951]

Well explained 80% satisfied ab tak ka sabse video on UA-cam about VFD !!!!!! Ab Aap Power card and Control Card Ko one by one Check karne ke liye video banaye Aur Power source ka baare me v explain kare

[@visionworldtech]

Sure we will make the video on that part also .

[@jabbarsinghrathore7621]

Wow so knowledgeable thanks for your efforts 👍

[@visionworldtech]

Thank you Sir

[@ninadraut5762]

couplers are actually opto couplers.these opto couplers get input pulses from microcontroller and give these pulses at their output to fire the gate of igbt.basically optocouplers isolate microcontroller from igbt
isolating highvoltage and low voltage side
