220 volt AC output sinus inverter circuit built on SG3525 smps control integrator Transformer used in transformer computer power supply (Ferrite CORE E Type)
The input voltage of the inverter circuit is between DC 10.5 Volt and 14.5 Volt. It can be used with battery. When the input voltage drops and over load warnings are given with buzer and led 220v output voltage, low voltage and overload can be adjusted.
Up to this day, many circuit diagrams have been published on this subject, but the output of this circuit can be considered very good ılı AC SINUS yap in the environment with the dear “ETE ev we had done with. Circuit board, I had prepared the installation scheme. Almost all the explanations are available on the schema. The transformer used is the var Ferrite CORE ide type bil E ilgili. The diagrams and dimensions are explained in the diagram. In the meantime, I think it is useful to remind of the transformer information. the same result may not be obtained.
Because of this kind of transformer of some of the characteristic values do not be the same, you do not intimidate, by changing the number of windings given, you can make the transformer in your hands. The circuit is operated from DC 10.5 to 14.5v. Low voltage, overload warnings are available. You can operate your devices up to 200W with this circuit.
The circuit file ” Circuit diagram + Printed circuit + Placement diagram + Bill of materials ” are available. I wish success to friends. Good luck with
Materials that are missing in the diagram and are given different values.
1-C24-33uF / 350v (to be connected between + 315v and the chassis)
2-C25-10uF (to be connected between the ground of the buzzer and the chassis)
3-10k given as R29-1k (connected between legs 1-8 of LM393)
4 Given as -10uF, C7 and C8 will be 1uF. The C11 supplied as 1uF will be 22uF (connected to the legs of the LM324 ..).
5-VRV The terminal of the voltage adjustment trimpot will be connected to terminals 12-13 of 556.
