I recently picked up an 8x8 Magnetic Sine Chuck for little or nothing (less than $20). No power supply, but no big deal, or so I thought. Unfortunately, I didn't notice that it's 220V DC, and all my power supplies are 110V DC.
Question is, what's the best (primarily inexpensive, but dependable) way to approach this? Use my existing 110V DC rectifier power supply to drive a 110:220V DC transformer? Or look for a surplus 220VDC rectifier? Other? There are a couple of local surplus shops that almost certainly have what I need, I just need to know what I'm looking for. I know quite a bit about automotive DC systems (quite a lot actually), and I know quite a bit about 110/220V AC 1ph and enough 220 3ph to get by. But most is anecdotal, not really engineering grade logic. I can do the research for general info, but it would help a lot to know the best of the several different paths to 220V DC output. I've never fooled much at all with transformers and rectifiers other than just to use them, so any help/education will be much appreciated.
