So electrolytics and their voltage rating is something of an issue for variable power supplies...

If we have 350V DC rated reservoir caps and we have our variable power supply turned down supply 80VDC for a few hours, and then we abruptly turn it up to 180VDC, our electrolytics are now 'formed' for the lower voltage, right?

What's the workaround? Switchable reservoir caps?
