DC to AC with IC555 circuit
AC to DC IC Series DC-AC inverter produces an output voltage alternating voltage network.
IC 555 configured for Low Frequency Oscillator. Frequency can be changed 1950-1960 change frequency meter Hz potens R4.
This DC-AC inverter schematic produces output AC power, and frequency. 555 is set to a low frequency oscillator, tunable in the frequency range 50-60 Hz, R4 potentiometer.
555 feeds output (which Q1 and Q2) to the transformer T1, a reverse filament transformer with the necessary step to turns ratio. Capacitor C4 and coil L1 filter the input T1, assuring that it is virtually a sine wave. Adjust the voltage of T1.
Output (in watts) you must select the different parts.
input voltage is anywhere +5 V +15 V DC, operating voltage CAP 2700uF adjust accordingly.
Q1 are the types of compensation: TIP41B, TIP41C, NTE196, ECG196, etc. Q2 types of parts are: TIP42B, TIP42C, NTE197, ECG197, etc. Do not be afraid to use another type of similar characteristics, only one transistor. .. 
Parts List:
R1 = 10K
R2 = 100K
R3 = 100 ohms
R4 = 50K potmeter, Linear
C1, C2 = 0.1uF
C3 = 0.01uF
C4 = 2700uF
Q1 = TIP41A, NPN, or its equivalent
Q2 = TIP42A, PNP or equivalent
L1 = 1UH
T1 = filament transformer selection
If everything works well. If not, relax and do not get frustrated. Check the following:
1. You have connected the filament transformer so contrary?
2. Otherwise, unplug the power cord and vice versa. If you have, disconnect the transformer and measure the voltage after the L1 and the earth.
3. Only if the bottom of this neighborhood is the same as the negative (-).
4. Q1/Q2 are oposites, e.i. NPN / PNP.
5. Is it 555 defective? Remove the pin from 3:03 R3 to control impulses.
6. Check the transistor to make sure they are intact.
Error: Pin 7 and 2 were reversed. The original pin was correct.

hi, it is so nice but, what is the voltage output of it and how much load of watts it can carry?
how to make this voltage output into 240v?.can you tel me?
I have looked for a circuit like this everywhere, can it be battery powered? Does it truly convert DC into AC?
Hi,
Can you please tell me how I can upgrade this to like 5KVA 10KVA etc.
how to use IC555 for other project?
what is input voltage of transformer T1 and tell me value of transformer plz
THANK YOU FOR YOUR GOOD PROJECTS SUCH AS INVERTERS DC -AC. WHERE I DON’ T UNDERSTAND ON THE DC-AC INVERTER ,CAN I USE THE NORMAL TRANSFORMER (TI ) AND I INPUT THE SECONDARY PART AND I TAKE THE NORMAL INPUT TO BE MY OUTPUT WHICH IS THE PRIMARY.
Thanxs free-electronics, your circuit is a perfect and a working one keep on the good work.
good day…thanks for this dc -ac inverter circuit but i have just one question…can i use a car/motorcycle battery as a dc voltage source?
pls can you assist me with an automatic swich-over back up power supply,rated 12v 1200w.
pls can you assist me with an automatic swich-over back up power supply circuit,rated 12v 1200w.
can someone assist me in finding a solution for the repair of my 600watt Dc to Ac inverter that produces low voltage even when the Dc battery is fully charged. Which specific component will i change on the circuit panel, Chopper transfer ,capacitor ,transistor ,resistor etc or what ??? an urgent answer please…
how many t
your circuit is a perfect! how many turns are there in both sides of a transformer?
what is input voltage of transformer T1 and tell me value of transformer plz
- T1 TYPE ARE USUALLY USE FOR ADAPTOR TRANSFORMER, STEP DOWN FROM 220VAC TO 3,4.5,6,7.5,9,12,ETC.

- POSSIBLE BREAK ON CAPACITOR AND YOUR TRANSISTOR POWER. TRY TO CHECK THE IC FREQUENCY ETC 4049, ETC.
your circuit is a perfect! how many turns are there in both sides of a transformer?
- NO NEED TO CHANGE THE WIRE OF TRANSFORMER. JUST TRY WITH SOME STANDARD ADAPTOR TRANSFORMER
which capacitors should iuse because i use slamic disk and the out put is DC
what is power output. how much watt power in output.
hiiiiiiiiiiiii your circuits is very useful please tel me full details of trasformers
Thank “”"U”"”"
which type of capacitors should i use
