True Sine Inverter (Idea)
Advertisements
This is an idea for a true sine inverter to get 120 or 240VAC from lower voltage DC. This could be handy for running a mini-fridge from your car all the way up to powering your house with photovoltaic cells and lead acid batteries. Most inverters found in stores use an approximated sine wave or square wave which is alright; but devices are much happier when they have a sine wave, especially inductive ones. After looking at a few Vector units, which are all square wave, and some filter circuits, I came up with a preliminary design idea. So far it’s just a block diagram. Maybe someday it may get a schematic or even built; but there are lots of projects going on around here.
