Sine wave Inverter Project


Recommended Posts

Since Class D Ampilifiers are cold amps or have 100% theoratical efficiency with upto 94% practical efficiency . it is very much suitable for a sine wave inverter design , however i was able to look up a site which is open source class D Amplfier Site

Please take a look

please take a look at the link i posted above , i think it is a simple and effective design. but i can't find how much power it is delivering

The archive notes say 102W into 8 ohms or 180W into 4 ohms. It quickly got very warm with 180W output and so the mosfets need better heatsinking.
Efficiency was about 86%.
Note that its power supply is positive and negative 50VDC. About eight 12V car batteries in series would power it.
