Welcome to European Tribune. It's gone a bit quiet around here these days, but it's still going.
By the way: the main innovation in the ABB system with two converters and a medium-frequency transformer is that the first converter deals with an input voltage that is too much for a single semi-conductor. I know little of the inside of home appliances, so I ask: do series-switched semi-conductors with sub-230 V limits appear in them?
