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.
