I have recently purchased a device that requires 1000w of power at 48 Volts. My next problem is how to power it.
I have found that manufactured power supplies are expensive, so I am wondering what the possibility is of building my own. Of course this device is going to consume quite high average, so could be quite dangerous. Ultimately I would like to build a variable voltage power supply so it can be used in multiple projects, at the expense of maybe taking on too much.
I have found a great power supply which could deliver 100 amps @ 12v - dangerous! It does however provide an isolated output from mains and is manufactured from a good source so I trust its quality. Next of course is how I would boost the voltage and supply amperage required - I am thinking of using either a manufactured step up buck converter or linear regulator (LM317AHV seems an interesting one: http://www.farnell.com/datasheets/1949043.pdf) and then a pass transistor to deliver the current.
Is this all possible or am I taking on too much? This will be my first attempt at building a power supply and with my luck has to be a bigger project than I would like (such high amperage and variable voltage functionality), so I am worried as to how to approach this.
Can I use a manufactured step up buck converter with pass transistor (haven't seen much info on this)? Is it difficult to implement a variable voltage linear regulator with pass transistor? Does the variable voltage requirement make this all too complex?
Much obliged for any help.
