12V to 230V DC AC Inverter Circuit

12V 230V Inverter Circuit Built on cd4047 cmos monostable/astable multivibrator integrated, the 12v battery voltage increases to 230v ac, the output frequency can be adjusted as 50hz or 60hz.

Input voltage 12V DC, Output 230VAC / 50 / 60Hz Possibility to change Square wave Output Frequency from 50Hz to 60Hz. Efficiency between 80-85%

This simple 12V to 230V converter circuit can be used at home, in the cottage, to operate compact fluorescent lamps, conventional fluorescent lamps, small motors, Small televisions.

It can be used not only at home and at the cottage, but especially in a car trailer, on a boat and wherever there is no 230V distribution network. The connection is very simple. The monostable flip-flop circuit 4047 operating in astable mode functions as a 50Hz rectangular waveform generator. Out-of-phase output pulses are available at outputs 10 and 11, which trigger four MOSFETs (IRF9540, IRF540) transistors connected to a bridge that alternately connects the winding of the 10V transformer to the 12V supply voltage.

With the specified values of the RC oscillator components at terminals CD 4047 1, 2, the accuracy and frequency stability is approximately 2%, which is sufficient for all the applications specified. It is recommended that the resistors R1 and R2 be 1% or less tolerance and the capacitor C1 should be multi-layer or radial as in the application.

12V to 230V Inverter Schematic PCB

With 40W transformer No-load voltage 260V, current consumption 400mA voltage on bulb 25W Consumption at 230V load 25W Voltage on 2.5A bulb 40W 3.8A consumption at 220V load

With 100W / 230V / 10V transformer No-load voltage 270V current consumption 800mA Voltage drop on 40W bulb 225V Current consumption with 40W 3.6A Voltage over 60W bulb 210V 4.8A current consumption

The inverter circuit can be used with transformers with 220V, 230V input and 10V, 12V output. The power of the circuit can be increased by using a higher power transformer. A 200W transformer has been tested without problems. Approximately 160w output power is taken

Better parameters, higher efficiency and less no-load current consumption can be achieved with toroidal transformers. For high power, the heatsink must be enlarged in addition to transformers over 200w Untested structure will require regulation for surplus

When the inverter circuit is unloaded, it gives about 260V voltage at its output. When the load is connected, the voltage drops to the optimal level. The distribution network has a voltage fluctuation tolerance of +-10%, which is 207V to 253V. For safety reasons, it is recommended to install the inverter in a plastic box.

Update; @seron from the forum redrawn and shared the printed circuit, thanks. It has not been tested, it was made according to the original PCB drawing, check it according to the diagram before printing, before applying. In addition, the source where the source site took the circuit was found and high resolution schematic and pcb drawings were added to the article.

CAUTION 12v 220v inverter circuit produces high voltage. Be careful with the capacitor connections. If you reverse the + – poles, there may be large explosions at high voltage, before operating the circuit, use the Insured Power Line, protective glasses.
