So basically I was writing down why a modified sine wave inverter or "pure" sine wave inverter is beneficial over a simple square wave inverter. I understand the fact that a square wave is comprised of many different and higher frequencies and these high frequencies cause more inductive reactance in the inductor. What I dont get is that it seems as though the inductor is seeing a constant voltage and current just for short amount of times and so is a constant voltage/current through an inductor a bad thing then? And if that is the case then why is a modified sine wave better than a square wave? because it spends less time at a non-zero voltage?
Building upon this I have read than transformers are less efficient and dissipate more heat when passing a square wave but I have to find a satisfy answer as to why this happens. I understand the power losses given the high frequencies present in a square wave and the formula for inductive reactance being dependent on frequency. what I don't understand is why more heat is created given that reactance does not dissipate energy as heat as resistance does.
thanks
