Thanks for your nice Attached file. I read full documents.
I try to make project by using MPLAB ASM , but there is lot of error. Please tell me which compiler used for "sn3_ups".
Also, I try to open "SINE_03 PCB File" but can not open. Please tell me which PCB design software used for "SINE_03 PCB File".
Sir, I am waiting for your kind replay.
please ..............

Dear MRahman sir
I found small similarity with CCS C compiler with your "sn3_ups". if program is written in CCS C compiler Please send me "sn3_ups.c". anowar.mieb26234@gmail.com
In My proteus Simulation Sign wave is not stable. Inverter Run on Square wave but MPLAB simulation shows it takes values from Sign Table but output is square wave. help me please about ccp1.
try and understand the way it works. the sign waves had been chopped into discrete numbers of 1 and 0 in time. so what you will have is a square wave as the output pin of the micro can either be one(1) or Zero(0). so by using a low pass filter at the output. you get sinewave output. if all is ok with your design.
.. regarding the compiltion with mplab -- it has
too many error, but inverter is working well, try to understand how the inverter works, then it will be easier for you to implement. thanks Mrahman.. please send me a copy of sn3_ups.c thank you
regard .. henry Nigeria.
Thanks for sharing, really appreciate this. But please i would love if u can help clear some doubt.
1. What are the terminal voltage of the transformers(the primary and the secondary when not used in the inverter circuit.
for the 24 volt version is 230 to 24v or 230 to 16v. considering the peak value of the battery voltage.
2. please can you explain how the feedback loop works with the voltage compensation. (how does the sinetable compensate for low or high output voltage.
3. how many times do u sample the feedback circuit and how long do u do compensation for the output voltage regulation.
are this the outputs from the logic gates,or the gate drivers?
if the second waveform is from the logic gate. i would say is ok and i could see sometime time difference between the two. that is good as its a means of good dead time between the mosfets when they switch.
Hello every one,
I try to do a practical simulation of this inverter but the feedback is not working. Has any body successfully implemented this inverter . see my attached simulation in the image below.
The circuit M Rahman post has some errors but the code was ok and the inverter is working very well i advice members to study circuit diagram first and understand how it works before building it
