Hello smijesh
Thanks for the reply bro. Can you explain how the oscillator works and how much frequency it is produced in this arangement,how is frequency effects the transformer and feedback system(how optocoupler effects pwm in oscillator circuit)..so how much frequency we have to provide at...

Hello
I have included a link which shows an smps power supply with 12v 5a output using flyback topology. But I need an alteration from this circuit 28v 1.5a circuit.Also please tell me the working of the feedback and a oscillations of power mosfet(as this analogy...
Hello Klaus
Thanks for the reply...I am sorry for didnt mention about the input. The input is 230v ac,preffering the circuit with flyback converter....I am looking for a constant 28v,1.5a at the output using flyback topology with feedback system....i have designed a circuit with astable...
Hello friends,
I am looking to construct a smps based power supply circuit of 28v,1.5a output with following specification.
1.power factor of .95
2.hiccup current protection
3.constant voltage output(feedback system preferable)
4. 10ms hold on time when there is no power at the...
Thanks bro,
I have already gone through this files but it seems something difficult that both pwm and square waves are generated at the output of h bridge ,hence I couldn't understand the way they managed the procedure, also is that inverter can provide 500w output although it has only 4 MOSFET...
Thanks bro,
I understood about the uploading of various files and images, But I am still waiting for the reply for my inverter project. Is there anyone kind to help me.
Hello benzt,
I can simply explain u transistor as switch(although it is a switching device).By giving small signals to transistor base junction the transistor switches nd there will be some current will flow from collector to emitter. The amount of current flow from collector to emitter is...
Hello friends
I am trying to make a 500w microcontroller based inverter for my home.I have some problems related to this issue (basically the losses,working and efficiency).I am using pic16f877a as the microcontroller but i don't have any idea of which kind drivers, MOSFETs and transformer are...
