Better Sine to PWM to sine

Your SPWM generation is wrong

@PrathikP All right! I can’t follow links in the mobile app, but I assume you’re linking to your SPWM circuit :) Thanks for the feedback! I’ll study it so I’ll get it right, lol. However, I do get a similar sine output in this circuit, is that just by chance and specific to that frequency? I mean is it functional at all or does it just seem like it kind of works? haha

Thankyou Billy, I forgot to remove the s in https. So trollis, the thing is that your SPWM must have a positive pwm half and a negative pwm half. In your previous circuit, the pwm always had a +15 to -15 V output, which isn't going to work. In this circuit, your pwm only has a positive output, which also doesn't work. When you want the positive part of the sine wave, you need a 0 to +V PWM and to get the negative half, you need a 0 to -V pwm. Then add the two outputs and filter it using an LC filter with a cutoff frequency of (ideally) 50Hz (but in reality you'd rather set it to something like 500Hz). Use a carrier frequency of 10KHz or higher

Thank you!
