Flash Pop Smoke Smell

That's something I'd like to understand better, too. For starters, why would you use a modified square wave to begin with? A square wave is 1/2 fundamental frequency, 1/3 3rd harmonic, 1/5 5th harmonic, etc, IIRC. Why would you waste 50% of your capacity that way, when it's so easy to use switching technology and a LC tank to smooth things out without significant losses? A 4th order bandpass filter is easily made with a series LC circuit, followed by a parallel LC tank, and that will appear to be resistive to the driving source.

Other than the fact that a modified square wave is the cheapest wave form that generally will keep the magic smoke in electronics... I'd always assumed that the extra hardware needed for a true sine wave (or something reasonably close to it) was relatively expensive since it only ever showed up on double conversion UPSes which also need significantly higher grade charging and inverter circuitry.
Did you ever see history portrayed as an old man with a wise brow and pulseless heart, waging all things in the balance of reason? Is not rather the genius of history like an eternal, imploring maiden, full of fire, with a burning heart and flaming soul, humanly warm and humanly beautiful? --Zachris Topelius Training a telescope on one’s own belly button will only reveal lint.
