# 12V 220V DC-DC CONVERTER SCHEMATIC CIRCUIT DIAGRAM

I’ve seen a simple high voltage circuit when mixing the circuit archive I wondered what would be the result with the pc power transformer after 1..2kv 🙂

CAUTION: Be careful that the circuit provides a high voltage circuit Do not operate without taking the necessary precautions 220v is not suitable for use in devices working with ac (tv, monitor, etc.)

220 volt 50watt lamp directly connected to the transformer output directly connected to the DC voltage measurement without using an fr107 fast diode I used a half-wave rectifier with the lamp connected while the 220-volt DC-DC voltage measured the load without being connected to the 270V fraction

At the transformer atx computer power supply used in the circuit out of power transformer small ones 🙂 EI28 I did not experiment with other EI33 Transformer but it is sure to work

The key component of this little voltage converter that changes a 12VDC into 220VAC is CMOS 4047, which is built inside this DIY 12V to 220V DC to AC converter. The 4047 is employed as an astable multivibrator; a symmetrical rectangular signal (square wave) is generated at pins 10 and 11 and amplified by two Darlington transistors before reaching the secondary coil of the mains transformer (2x10V/60W).

The output frequency can be changed between 50Hz and 400Hz using P1. Although it is not included in any professional dc to ac converter, it can be utilized to power some household appliances. It’s important to note that the output signal is square rather than a sine wave. As a result, it cannot be used to power TVs, laptops, or monitors. Only use it for lighting, power tools, and other low-cost items.

Fr107 is a Fast Recovery Rectifier diode, designed specifically for circuits that need to convert alternating current to direct current. It can pass currents of up to 1 A, and have a peak inverse voltage (PIV) rating of 1,000 V.
