What the advantage of a DC supply, if it is not used to integrate many
cycles of a power supply to charge a cap to a higher voltage than would be
otherwise possible. Such as is done with a camera strobe light. The
milli-watt average power inverter oscillates hundreds or thousands of cycles
to integrate watt-seconds power in the photoflash cap, which is then
discharged in milli-seconds for kilowatt power levels.

You get to use a much cheaper, smaller, compact supply because you are not
going at a high repitition rate. If you tried, the solid state drivers would
burn, inverter transformer saturate and capacitor would explode.

Radar and linac's are DC appliances.
