The traditional transformer is trending towards pocketsize and noiselessly in inverter using high-frequency link technique,but the control circuit becomes difficult to be designed.
The controlled circuit can then connect to other circuits, or to something like a motor, which might increment a count on a gear, like in Hollerith's tabulating machine we talked about last episode.
