I just love this,component list and construction of a watt or watt power inverter. The voltage present at the ohms resistor is enough to turn it on…. Please take advice from electronic hobbyist nearby you.

Is this a modified sine wave output. I realy appriciate your afforts to communicate such type of information to tecnical people.

SMPS Controller

Check the quality of the inverter ka524 and battery capacity. Same problem with me too. Can someone answer me please I need some help here. Hi Oyinz instead of using wire for transmitting data from one system to other, you use optics to do the job so that you get isolation between sender and receiver.

Hi Sim you can use for inductive loads but limit the load to watts maximum. Do I missed something here? Looking for your reply just now.

You can use 2N OR datsheet instant of 2n During this period pin 11 will be low and its succeeding stages will be inactive. Let me know if you have any other doubts.


Mujhe ye janna hai k is circuit me 2 transformer kyon use kiye gaye hain? Please, I want you to discripe how I can use voltmeter to measure the output of oscillator at pin11 and pin14 of IC SG Sir, I have requested for a transformer with va which is the T2 V now what about the T1??

Please do that and see if it will work. I connect the output from daatasheet bc directly to the gate of the mosfet. That you please leave it to a good transformer designer. R11 limits limits the current through the indicator LED D2. Not Sure Why need to add this 0. I also remove those two diodes….

The transistors heats up tremendously. Yes you can use more transistors in parallel to achieve higher power output. As a result a voltage is induced in the transformer secondary due to electromagnetic induction and this voltage contributes to the upper half cycle of the V output waveform. When my primary side of transformer is kept open Between centertap and 12 Side and check the voltage reading with my multimeter, it shows Hello Thanks for the schematic can you send me kq3524 sch file, Plz.

Pls sir am happy for this circuit i had a question that can i still remove the 2n transistor if i had no volt drop sir pls i am waiting. I use mosfet mine is still working…with mosfet we can eliminates Q4 to Q6 and so on. That inverter was working and it just stopped whilst working. Pls bro,have tested this circuit and it worked out perfectly well. Resistor R2 and capacitor Ks3524 sets the frequency of the ICs internal oscillator. Because the output at pin 14 and 11 reads 3.


Hi everyone, my eyes are not up to par these days, so if I am wrong, ignore this question and remark.

Hello…this circuit is a great one…I modified mine by replacing those transistor 2n and 2n with 2 mosfet in parallel irf this mosfet has max of 10v gate to source voltage datashret is capable of handling A see their datasheet. I have seen many diagrams and yet to see a inverter project for a modified sqaure wave but with stable v at its output.

It is hard to find, use 2 x 2N instead or 3 x 2N Hello sir, I need all the details about inverter can you pls datssheet me about that. This includes Q1, D1, R3,4,5,6,7 and C2,3,5.

Fatasheet you again for the schematic! Thanks for the detailed explanation of how the circuit works, which I have fully understood. C8 is a filter capacitor for the voltage regulator IC Kindly expanciate this please:
