Tool/software:
Hello,
I am trying to design a board to test some control methods for a packed e-cell inverter topology (something like this)
I have been looking into the reference design above TIDA-00199 and it uses a single transformer for generating power rails for three arms of a conventional 3-phase inverter. The voltage rails for all the TOP IGBTs are isolated, whereas the voltage rails for all bottom IGBTs are combined.
But in my case, I don't have switch pairs as in full bridge inverters so how can I use this transformer or reference design in the above PEC inverter ..? Or is there any better way to create a bias supply for that many switches?
Or should I just use non-isolated gate driving? is there a reference design for this case?
I thought of using isolated DC-DC modules but in that case, I will be using one for each switch and that will increase cost and complexity ..
Thank you all,
