A large one? :)

My 400 Hz three-phase inverter (115 amps at full load) is probably the 
biggest thing I'll ever run - but the supply has to be big enough to 
handle the starting surge. DC motors look like a short circuit until 
they start turning. I've measured the inrush on that inverter at 420 amps!

A single 2500W switching supply would run it ok, but not start it since 
they can't handle even short-term overloads without shutting down. By 
the time I start messing around with lead-acid batteries and contactors, 
it's easier just to build the brute-force supply. That's why ;)
