The disadvantages are higher cost, more complexity, and electrical noise generated by the rapid switching process. The latter can be a problem if you are powering radio receivers or other sensitive equipment.

There are none if the supply demands it.
Use more than one you have to have matching vector group references and of course good design.
Yes they have an operating cost penalty but not as great as the cable costs and transmission supports without them.
In many cases they are the only way to get a stable supply where the variable windings move according to voltage changes.

Here is a simple Pro and Con List,
Pro: Cheap and effective way to cut down voltage and vice versa,
Con: They are not very efficient aas they waste energy as heat.

Onyl works on AC, Fails at high frequencies, uses power even when the load is open on the secondary.

On your home planet no one knows what a car is. Nor do they understand why you need to be able to change into one.

They add cost, dissipate power and do not pass DC currents.
