Dear Members,
I have designed Pure sine wave inverter successfully for 400 W load, by using SG3525 and then IR2101 for DC to AC conversion . In last step i have designed LC filter for pure sine
switching freq of Mosfet : 16kHz
Mosfet used in DC-Dc converter : irf3205
MOsfets used in switching : IRF 840
Mine main issue that when i connect resistive load of any value i got very Good Pure sine wave , but when i connect inductive load , Sine wave distorted. i have tried to understand problem alot but still didnt .
LC filter:
Capacitor : 1 UF
inductor : about 4.5 mH

Any helpp plz

 

You now have FIVE THREADS about this same topic, and you have not posted ONE SINGLE SCHEMATIC of your circuit, despite NUMEROUS requests to do so!

WHY do you refuse such a simple request from people who are trying to help YOU?

YES, I AM ANNOYED AT YOU, and for good reason!

 

I m Sorry for it . I will post whole scemetic . Then will ask little bit about it . Thanks for ur care sir

 

I have summarized your project in
http://forum.allaboutcircuits.com/showpost.php?p=652021&postcount=12

Is this correct? Would you please clarify the questions there?

 

Sir Thanks alot for ur such help . it is little bit change . I will upload my whole scematic and steps tomarrow in this forum then will ask again . Thanks alot sir Ramad
