TL494 1000W Regulated INVERTER Circuit Link:


Hello viewers. Today I'll show you how to make a Regulated Inverter (DC to AC Converter) to step up 12V to 220V with possibility of limited range adjustment. The circuit is based on the TL494 General purpose PWM driver IC. With this, you can also alter the shape of the output AC waveform and vary the dead-time to get a modified sine wave AC of varying RMS values.
For the Transformer use a 12-0-12V to 220V AC one. If you Salvage one, retain the original mains primary winding if its not damaged, then make your own secondary center tapped winding (it will be the primary afterwards). Make about 10 turns and connect the original primary to mains, measure the voltage on your custom winding, and by relating the mains voltage, output voltage and custom winding turns, you can make an accurate estimate on the number of turns of the original mains winding. Now complete your custom winding to give you a step up ratio of 1:20.
I hope you enjoy. Don't forget to LIKE, SHARE and SUBSCRIBE for more.
