Cool DIY Video : How to build a Homemade 12V -120V Inverter using an Old Microwave Oven Transformer (MOT)


    This video demonstrates how you can convert a microwave oven transformer into a 12VDC to 120VAC power inverter. This inverter in this video is rated at 75 Watts using the current transistor/resistor setup. The stranded 10ga windings are capable of 300-400 Watts. In order to produce that much power, you would need to use more powerful transistors/mosfets, or add more transistors in parallel with the first set using a low resistance emitter balancing resistor(around .1 ohm/10W). The frequency output is between 150 and 230Hz(Value can vary depending on your setup). Even with this higher frequency, you can still power incandescent lamps, and many electronics because the incoming AC will be converted to DC anyway
