If possible please send me as early as possible. What modifications will I have to make to the above inverter? Previous post Next post. Sir I trying to assembling this circuit.

Preset R1 can be used for fine tuning of the oscillator frequency. If we are going to get that complicated,at least make it better. Please send the circuit.

Soon as I connect it to the transformer, the voltage accross the terminal on my primary drops to 6. Is this inverter waveform suitable for all kind of loads?

I realy appriciate your afforts to communicate such type of information to tecnical people. This circuit works well and many have successfully assembled it. When my primary side of transformer is kept open Between centertap and 12 Side and check the voltage reading with my multimeter, it shows Thank You for posting the circuit on your datasjeet, PWM daasheet circuit: Hi Sim can be used. Sorry for this question what is mosfet and how can i mount this circuit on a breadboard.

Check the quality of the inverter transformer and battery capacity. Irf wud be enough?. I have design the above circuit that is w pwm inverter,only i have replaced the transistor by mosfet but i satasheet not getting the desired output that is v instead v,Even by adjusting the preset so please kindly help me to get down of this issue.


Thank catasheet for pointing the mistake.

KA3511DS, KA3524, KA3525

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. Let me know if you have any other doubts. What should be the number of turns for the primary and secondary of the transformer windings? Sir, it is realy a good apparunity to learn about electronic circuits. Please reply to my mail. Pls can you give a full explanation of the modified and it connection circuit. But I would like to ask you, do you somehow have some osciloscop plots of the output waveform?

Not even for 24 minutes how could be for 24hrs???!!! PWM is used to keep the output voltage of the inverter steady irrespective of the load variations. Can someone answer me please I need some help here.

You give the spec to them they will take care. Try it and give me feedback. Constructors who have basic knowledge about voltage regulators might not have made the mistake and would have completed the project successfully. SG is an integrated switching regulator circuit that has all essential circuitry required for making a switching regulator in single ended or push-pull mode.

Because the output at pin 14 and 11 reads 3. Pleae sir, can I convrt the Watt inverter to Watt kaa3524 more by just inceasing number of driver transistors or mosfets and the suitable transformer T2 without alter the oscilator and the feedback circuits, thanks.

Thank you keep up the good work. Reply to Ed There is no problem with the circuit diagram.


Where is the listed in the related description? Hi Mike the output will be pure square wave. Hi Prakash all connections shown as ground to be connected to negative adtasheet the battery.

datasheeet Thanks alot more grace to your effort. Hi Sim this inverter is more effficient kz3524 per load requirement the output is pumped. Dear Sir i made that inverter it produces a v well with neon lamp but when i connect it to a computer or LCD tv the output became not stable the frequency became not stable decrases and increases.

Pls where can datashwet get the component for this inverter in nigeria at offa kwara state. Circuit diagram of W PWM inverter. It is hard to find, use 2 x 2N instead or 3 x 2N If it is possible to send me a procedure of testin of transistor and other semi conductors in a circuit or out of circuit by testing meters. C10 and C11 are meant for bypassing noise from the inverter output.

I find this type of circuit and now got it thanks for post this circuit. At oscilator side there are GND at 2N emitter which line can this be connected. Please, I want you to discripe how I can use voltmeter to measure the output of oscillator at pin11 and pin14 of IC SG Hi Sim it depends on the lamination its permeability etc. Do I missed something dataeheet I use mosfet mine is still working…with mosfet we can eliminates Q4 to Q6 and so on.
