I have built several square wave and modified sine wave inverter, but still have challeges which i want help before i start experimenting switch mode sinewave inverters;
my challeges are;
1. my output is not as good as those commercial modified sinwave inverters, this is very obvious when using ceiling fan;
2. when i plug computer system the voltage swing up to over 300volts;;
please i need help can somebody help me with a good modified sinewave 50hz inverter circuit; pls you can send to my email; "markotech2020@gmail.com" thanks
yea, i have got the problem solved, for those who are looking for a 1000watt modifined sinus inverter, should mail i will give them my complete design it works great with all my protections, low batt, overload, over heating
This is just wonderful..Could you manage to send me the schematics diagram with the modification built in?
In case you have PCB design finalized , can you scan this and send me??Thanks
The low pass pie filter needed for deleting harmonics needed has to be tape wound iron cored choke and bipolar capacitors ...is that helpful to your output stage ?
I tried it successfully .
