Analog SPWM Card for Sine Wave inverters || Generate SPWM control signals for H-Bridge
Hello everyone!
Thank you for tuning to my channel. This video is about creating and demonstrating the concept of SPWM signal generation which can be used to make pure sine wave inverters!
This entire project is made out of discrete analog components and there is no use of any microcontroller or ASIC. It's a completely analog circuit but generates perfectly stable 50Hz signal.
There are a total of 4 outputs from this card which can be used to drive H-bridge and create an AC waveform at the output of an inverter.
Please share your feedbacks and suggestions in the comments below.
Support my channel and let me know if you want me to make a detailed video on the working theory behind this card.
The documentation can be found at : www.utsavrshah.in/

Hello everyone! In this short video I will be testing this cheap but useful bluetooth audio receiver module that is capable of providing stereo outputs. This module can be connected with an amplifier stage to enhance the audio and use it in portable speaker systems. For my test I have used an amplifier based on the 8002 IC and the results are impressive! Do let me know in the comments if you ha...
DIY H Bridge Circuit for Inverters || Convert DC to AC using this module
มุมมอง 17K2 ปีที่แล้ว
Hello everyone! Welcome to my channel and thank you for stopping by. This video is about creating a very simple H bridge circuit that is essential for converting a DC voltage to AC. I have used this module to convert 220V DC to modified square wave AC signal that can eventually be used to drive AC loads. This H bridge is controlled by my DIY TL-494 based control card that generates accurate 50 ...

Can we attached a 12v smps module with input of 220dc to 12v dc for powering the ossilator? 3. Can we add some feedback circuit for steady 220vac output? 4. How to get sinewave 220v ac from it.

      1. Yes you can connect 200V DC coming from solar panel to H bridge. But the voltage may not be stable due to solar voltage fluctuations. 2. You can use any 220 to 12V smps based adapter to power the SG3525 3. In my circuit I have a provision for feedback in DC to DC conversion section. If you want a feedback in stabilization of 220V of solar then you may need to purchase a solar controller or a buck boost converter capable of handling that voltage levels. 4. You can use a H bridge circuit and EGS002 module to convert this DC in sine wave AC
