Hi, i'm making the board for an inverter, the specifications are
voltage rail 300V and maximum current of 40A (the current in fact will
be lower maybe 20A), here you can see the first rough copy of the
layout http://img521.imageshack.us/img521/8744/ir2110fh8.jpg, in the
left you can see the tracks and in the right the components, there is a
hcpl2530 and an ir2113, the rest of components are capacitors,
resistors and diodes, the layout is not finished so don't care about
the thin tracks that you can see in the lm7815. So my question is what
do you think about the layout? is gonna work?, what can i improve.?....
I have read in some places that i need a really big copper plane for my
gnd, but i'm not sure what really big means, i have readen the an 978
and in the figure 7, connects the rectifier board via twisted wire to
the power circuit board which has a power line plane and a gnd plane,
so this mean that have i to put a board with a gnd plane and with a
power line plane and then connect this board to the board with the
igbt's?, i hope that everybody undestand what i say.
There will be a board only with the igbt's and i will connect this
board to the board with the ir2113 with a wire, any special cares
should i have to connect the gate of the igbt's with the ir2113?.
Thanks so much in advance.
