From Satellite Power Buses to 800V EV Fast Charging: Why Does Higher Power Favor Higher Voltage?
As satellite payloads consume more electricity, power systems must deliver more power to onboard equipment. Electric vehicles seeking shorter charging times must also receive more energy through their charging ports in less time. If the supply voltage stays the same, both demands drive up current. Higher current increases resistive heating. To control temperature rise and…

In the Age of Space Computing, Why Is Energy Both the First Opportunity and the First Barrier?
On the ground, when computing capacity falls short, more servers can be added, the grid can supply more electricity, and additional cooling towers can be built. In orbit, however, there are no power outlets and no air to carry heat away. Every model inference, image-processing operation and inter-satellite data exchange ultimately becomes two things: electricity…
