how much of that did you follow? i see that in their document they have two big planes for the bus bars that connect the igbt's, and yours are only parallel bars. they also spread their igbt's out for better heat sinking, but i had read that it was better to mount them as close to each other as possible, so that the devices drawing more current would heat up and bring the adjacent ones up to temperature as well. just curious, your design looks great. i'm probably gonna build something really close to it here pretty soon. i'm thinking that i'm gonna go with a larger number of smaller capacitors though, to try to keep the overall size of the box down some.
