I'm not familiar with high end transformers, but microcrystaline does not sound familiar. Expensive of course, but does it shed heat well?

Oh, yeah, custom liquid cooled heat sinks. We were only trying to push 800 amps or so, but still lots of heat. And the microcrystalline is really good at not generating heat to begin with. Much lower loss at high frequency than silicone steel.
That teardown was for the 2013-2016 Fusion hybrid. Very similar to the Chevy Volt. The more I look at pictures on eBay of parts that purportedly are first gen inverters, the more I think it's buried in the transmission.
