Hi, i realized a pwm inverter (full bridge) with these characteristics:
Vbus=245V
Vrms_out=150Vac
Iout=2Arms
Fout=50-200Hz
Fswitching=25KHz
PWM method bipolar
Now the problem is the LC filter... I need a method to design the filter inductor...
I try to follow the powder cores catalog of MAG-INC
https://www.mag-inc.com/design/design-guides/inductor-design-with-magnetics-powder-cores
but i'm not sure the data i use for design are right (for example i don't know what is my DC current and what parameters i have to take into account when i design an inductor for pwm inverter).
Another problem is inductor size... i need a smallest size inductor. :fight:
Could you help me with a guide to design this inductor?
Thanks
