I managed to make variable voltage and current for dummy load using IGBT with PWM control from Arduino, I plan to use the output as a variable power supply. The output from IGBT is a square wave so I plan to use lLC low pass filter from IGBT output to make it pure DC.
How to determine/calculate the spec of inductor and capacitor for up to 100A usage? I tried to simulate with Multisim and tried different values and get 10mH and 4700uF. Is there any issue to apply this?
I found a shop that can make custom inductors, I just need to enter the value of inductance and current and it lists several types with different turns and resistances but same inductance and ampere. I'm not sure with the physical size, it states really small, is the spec legit?
