Hi everyone!
I start to build my power section of my controller.
The pcb is "hand-made", support 12 TO-3P IGBT, 6 electrolytic capacitors and the connectios of the bus bars and motor legs I made with copper bars.
I am anxious to finish and test.
with respect to the control board, I don't fabricate yet, but it is the design of Paul with some modification to components that get in my country and all SMD.
if I may a query, talking about power contactors of battery bank, I understand that we need two, one has preload resistance, but do not quite understand what´s the proper connection diagram.
I appreciate if anyone can give me a hand.
