Weird inverter transformer

[Tim Williams]

On a forum, a poster discovered this defective inverter unit on a Sony
Vaio. I've never seen a device like this before, so I'm bringing it here
for discussion.

What is the black thing? I presume a ferrite transformer of some sort, but
I've never seen one built with metallization before. What's inside?
