How charging is done in Transformer Inverters
A transformer inverter is normally able to convert 12V, 24V or 48V DC to AC through h-bridge and stepped up by the transformer to get the required AC output which is a bit straight forward.

As an inverter repairer, I have always questioned how charging works since it can't be a simple reverse step-down network since AC mains will vary, and precise voltages are needed to...

using Swordfish but the matrix fails
been hacking at this code and thought I got it correct but the matrix is supposed to decrement from 12 to 0. Since Popcorn left this site is kinda borening but helpful.

industry specification standard for differential line
Hello , I have several PCB's with 10 inch and 5 inch lines as shown below.
I understand we take (S21_10 inch_dB-S21_5 inch_dB)/5 and get loss per inch.
but thats not all .
As you can see in the plot below I was written 90 line on the PCB.
Few questions:
1.Is there a way using S-param to recreate this line impedance?
2.I know that material can be not unif...
