  Nobody should underestimate the difficulty of inverters. They are hard to make properly, and mains voltage ones are frickin' dangerous too.

  I want ElectroBoom to do a video on a DIY Pure Sine Wave Inverter, so that I can see how badly this thing can blow up.

  The amount effort you put into this video is astonishing, it makes me guilty for not supporting you other than watching. Sourcing the parts on your own must be such a real pain in the ass to do, and the fact you said <i>&quot;it doesn&apos;t blow up&quot;</i> multiple times clearly tell us you must be very happy with your hard work!<br><br>And oh, the principles of sPWM looks real similar to class D amplifier, only with some feedback inputs. Now I remember my silly idea years ago, using audio amplifier with step up transformer to make a sine wave inverter because back then, sine wave inverter was so expensive, it&apos;s literally unaffordable but today&apos;s sine wave inverter are getting cheaper and more affordable, there&apos;s no point in making your own with the risk it poses. Seriously, just get yourself a proper one.

  You have a lot of Chinese fans and we can help you translate the manual.<br>其实我们阅读英文的datasheet的时候也很痛苦的。

  Well....thanks for taking one for the team, &nbsp;a lot of hoop jumping in this one.<br>And the technical term of the day: &quot;it doesn&apos;t blow up&quot; <br>Cheers

  Hi! Nice video as always! But i think you used the wrong pcb for the thing you&apos;re trying to do! This pcb was made for the version where you put 400V in the board from a different source. You used the same compoments for the version with the iron core. The IRF840 are high voltage, low current mosfets with a BIG RDSon so thats why you had so much idle consumption. Try using the IRF3205 like they said in the datasheet with 8mOhm RDSon and bigger current, even in parallel! Also the transformer should be 8V to 220V and not 12-220 :D
