1. The application
2. Environment
3. Duty Cycle
Ferros can be tailored to have an output that is at times called a "quality square wave", which is easily rectified into low-ripple DC.

RE: Ferroresonant transfomers
Many years ago I was on an Ampex VR2000 training course and the lecturer regaled us with the tale of a company in the UK who were recording programs for US consumption using 525/60Hz NTSC.
For some obscure reason the company decided that it would be a spiffingly good idea to feed the VR2000 with 60Hz instead of 50Hz (which is what we have in the UK).
Sadly the valves (vacuum tubes) in the machine were fed from a ferroresonant transformer designed for 50Hz (odd that).
So the heater voltage on 60Hz was now somewhat more than 6.3V.
Oooops, expensive things those valves & hard to find...
