This is the IGBT version, so the newer one. It looks a lot like the AC controller .. there are 3 IGBTs .. but the outputs are in parallel and the current sensing is done as a group and not for each. It does high side switching for the DC motor instead of low side. If you tie the other motor lead to the +DC bus instead of the -DC bus, the controller does not appear to work.

Paul has been calling one of them Diahrea (I think it's the DC one), and Stinky diaper is, I think, the AC one. A marketing disaster if ever I saw one .. but they are his designs!
