"Figure of Merit" in pulsed applications vs "efficiency"
in linear applications.

Any (???) device can produce more peak power in pulsed mode than
continuous, because it spends less time in the region where it
dissipates the most power.


RMS power is measured in heating ability versus DC.

There is no such thing (other than in a mathematical sense) as RMS
power. Voltage and current can have RMS (root-mean-square) values.
Squaring voltage and dividing by resistance, or squaring current and
multiplying by resistance produces the //average// power.


And FOM is used (by me) because the efficiency is above 100%.
