    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!
