The ionocrafts or "lifters" require high voltage to operate, in the thousands of volts. The power supplies used need transformers. These are heavy though, because of the iron-cored transformers.
There are lighter air-cored transformers however. But what is the efficiency of these compared to the iron-cored?
I've been informed it depends on the frequency. But keep in mind this is for an application in the lifters that needs to be converted to DC. So use whatever frequency that allows a lightweight conversion to DC.
