Inverter | 12V To 220V | 40W DC-AC Boost Module
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.

Hi. In today's video tutorial I'll show you how to make a 12v to 220v DC to AC inverter with a power capacity of at least 600 watts. The circuit is built around the SG3525 pwm IC, which with its unique features makes the circuit simple and reliable. The inverter circuit is a low frequency type (typically 50/60Hz) as per recommendations for most countries. With this in perspective, the transformer must be a low frequency Iron Cored one with a power handling capacity of 600W or more. The obvious transformer choice would be a reworked MOT (microwave oven transformer) due to their easy availability and solid power handling capacities, or just any other transformer will work okay. A H-Bridge makes it even better because it eliminates the need for a transformer with a center tap, and also ensures you can achieve high power output levels by using powerful mosfets.
