A 3000W energy provide usually conjures up pictures of giant steel packing containers with noisy followers pumping air over huge warmth sinks, however this Intel reference unit blasts that concept out of the water, or relatively retains it cool, as a consequence of a water cooling system that retains every little thing good and clear.
Intel engineers designed this beast of a tool for knowledge facilities and servers, the place squeezing as a lot energy as attainable right into a small area is the secret. It accepts a big 240-volt AC and outputs an inexpensive 12 volts DC at as much as 250 amps, appropriate for 3000 wattage.Water flows by way of the again of the unit through quick-release fittings, carrying warmth away with out the necessity for a loud inner fan or conventional warmth sink fins, and the complete factor stays sealed and silent with no inner transferring components, counting on exterior coolant to maintain issues from overheating.

Inside, issues get slightly extra difficult as a result of the enclosure is a strong black field with no vents to talk of. When the screws are eliminated, you’ll uncover two chunky circuit boards jammed along with a big chilly plate crammed in between. The elements all push in opposition to the chilly plate utilizing thermal pads, and the circulating fluid then transports the warmth to the surface world. The configuration works effectively to separate chores, with one board dealing with energy issue adjustment on the enter aspect and the opposite dealing with the first DC-DC conversion bit.
Enter safety is the primary precedence, with fuses, surge arrestors, steel oxide varistors, gasoline discharge tubes, and common-mode chokes all doing their half to maintain disagreeable little shocks from the mains provide from inflicting points. Following that, bulk capacitors are used to easy out the rectified line voltage, guaranteeing that it isn’t unsteady or unpredictable. The ability issue adjustment step, however, employs a neat method referred to as an interleaved totem-pole topology to cut back ripple and improve effectivity. The GaN transistors in that half are from Texas Devices and have an inexpensive 600 volt ranking. They’re additionally fast-switching (which is sweet) and low-loss, enabling it to realize the unit’s 80 Plus Platinum certification
The ability is subsequently transferred to the phase-shifted full-bridge part on the opposite board. Silicon carbide MOSFETs are the high-voltage switching elements right here, paire with a transformer that graciously lowers down the voltage for us. The litz wire on the principle aspect is wound to cut back sign loss because the frequency will increase, whereas synchronous rectifiers on the secondary aspect work their magic to supply even higher effectivity. The output filtering is then supplied by a big inductor and 9000 microfarads of polymer capacitors, all working collectively to supply a clear 12 volts DC on the output.
In fact, there should be some management circuits in there someplace to maintain issues working easily; a Texas Devices C2000 microcontroller manages the PFC stage, whereas a PIC24 displays total supervision. To maintain issues good and protected, there are digital isolators (that are actually sensible, in my view) and auxiliary flyback converters that present standby energy as mandatory.
Among the design selections on present listed here are fairly spectacular, because the chilly plate design permits the unit to chug out a decent 2500 watts per liter, as that’s a whopping 250 occasions extra energy per liter than the common air-cooled provides, which could solely scrape in at round 800 watts per liter, however utilizing superior semiconductors like GaN and SiC actually helps to maintain losses to a minimal. Nevertheless, it’s the water block that also proves important at full load the place losses whole round 300 watts.
